Throughout these Terms of Service, the terms “MARSTEN,” “we,” “us,” and “our” refer to ZENTARA BRANDS LIMITED.

MARSTEN provides this website, online store, products, content, customer-account features, tools, and related services, collectively referred to as the “Services.”

If you do not agree to these Terms, you must not use the Services.

We may require reasonable verification before changing account information, discussing an order, or taking action on an account.

We may suspend or close an account where we reasonably suspect:

Unauthorized access
Fraud
Account misuse

Repeated payment failures
Unresolved payment disputes
Violation of these Terms
Other unlawful or harmful activity

Everyday household wellness

Nothing available through the Services constitutes or should be interpreted as:

Unless a specific claim is expressly stated, appropriately substantiated, and legally permitted for the particular product, MARSTEN products are not represented as being intended to diagnose, treat, cure, or prevent any disease or medical condition.

General references to comfort, relaxation, recovery, movement, massage, heat, light, stimulation, monitoring, fitness, or wellness do not guarantee a medical or clinical result.

You must review and follow all product instructions, warnings, labels, limitations, and safety precautions before assembly, installation, or use.

Where applicable, you are responsible for:

Correct assembly and installation

Damage, malfunction, or injury caused by misuse, improper assembly, unauthorized modification, unsuitable storage, neglect, or failure to follow instructions may not qualify as a product defect, subject to applicable law.

7. Orders and Contract Formation

Submitting an order constitutes an offer to purchase the selected products under these Terms.

An automated order-confirmation message confirms that we received your order. It does not necessarily mean that the order has been accepted, verified, or dispatched.

An order is accepted when we:

Send a shipping confirmation; or
Otherwise expressly confirm acceptance in writing

Before acceptance, we may review the order for:

Product availability
Payment authorization
Address accuracy
Fraud indicators
Identity or transaction verification
Shipping eligibility
Quantity or resale concerns
Pricing or listing errors
Legal or regulatory restrictions

We may accept, decline, hold, or cancel an order in whole or in part where reasonably necessary, including because of:

Product unavailability
Payment failure
An obvious pricing or listing error
Incomplete or inconsistent information
An undeliverable or restricted address
Suspected unauthorized payment
Fraud or security indicators
Unusual ordering activity
Quantity or resale concerns
Policy abuse
Technical or operational errors
Legal or regulatory requirements

If we cancel a paid order before fulfillment, we will issue the applicable refund to the original payment method.

We are not obligated to fulfill an order merely because payment authorization was approved or an automated confirmation was generated.

8. Customer Information and Order Responsibilities

You must provide complete and accurate:

Full name
Billing information
Shipping address
Email address
Telephone number
Payment information
Apartment, suite, unit, gate, floor, or access information
Other information reasonably required to process and deliver the order

You are responsible for reviewing this information before submitting the order.

You must ensure that:

The delivery address is accurate and accessible.
The recipient is authorized to receive the package.
The location is reasonably secure.
Building or delivery instructions are complete.
You monitor tracking and delivery communications.
You respond promptly to reasonable verification or carrier requests.

We cannot guarantee that an address, product, quantity, or other order detail can be changed after the order has entered fulfillment.

We are not responsible for delays, additional costs, failed deliveries, or losses caused by incomplete or incorrect information supplied by the customer, except where applicable law requires otherwise.

9. Currency, Prices, and Taxes

Unless expressly indicated otherwise, all amounts displayed by MARSTEN are stated in United States dollars (USD).

The price applicable to an order is the price displayed in the order summary when the order is submitted, subject to correction of an obvious error.

Applicable:

Shipping charges
Optional service charges
Discounts
Taxes
Other required fees

will be displayed before the order is submitted where required.

Prices may change without notice before an order is placed.

If a product is displayed with an obvious typographical, technical, or pricing error, we may:

Contact you with the corrected information
Cancel the affected product before fulfillment
Issue a refund if payment was already collected

We will not increase the price of an accepted order without your agreement, except for a correction or charge required by law.

Your bank or payment provider may apply:

Currency-conversion rates
Foreign-transaction charges
Payment-account fees
Other charges determined independently by that provider

MARSTEN does not control or receive fees imposed independently by your financial institution.

10. Promotions and Discount Codes

Promotions, discount codes, gifts, and special offers may:

Be subject to separate conditions
Apply only to eligible products
Be limited by customer, account, address, or household
Be limited to one use
Require a minimum purchase
Exclude shipping or optional services
Expire at the stated time
Be withdrawn before an eligible order is submitted
Be unavailable in combination with another offer

Unless expressly stated otherwise:

Discounts cannot be applied after an order has been placed.
Promotions have no cash value.
Promotional balances cannot be redeemed for cash.
A free item must be returned when required by the Return and Refund Policy if the qualifying purchase is returned.
The disclosed or reasonable value of a missing promotional item may be deducted from a refund where permitted by law.

We may cancel or restrict a promotion where there is reasonable evidence of fraud, technical error, duplication, or abuse.

11. Payment Authorization

We accept the payment methods displayed as available during checkout.

By submitting payment information, you represent and confirm that:

You are the authorized payment-method holder or have the holder’s express permission.
The billing and payment information is accurate and complete.
The payment method is valid.
You authorize MARSTEN and its payment providers to charge the total displayed at checkout.
You authorize reasonable transaction, address, identity, authentication, and fraud-prevention checks.
You agree to pay all charges associated with the order.

Payments may be:

Authorized immediately
Captured immediately
Temporarily reserved
Captured after verification
Declined or cancelled by the payment provider

A pending authorization is not necessarily a completed charge.

If an order is cancelled or declined, the time required for a pending authorization to disappear is determined by the customer’s bank or payment provider.

We do not control how quickly a financial institution releases a pending authorization.

Payment information is processed through Shopify and authorized payment providers. MARSTEN does not directly receive or store complete payment-card numbers or card security codes through its ordinary business systems.

Additional payment terms are available in our Payment Policy.

12. Fraud Prevention and Transaction Verification

To protect customers, payment-account holders, and our business, orders may be screened using automated and manual fraud-prevention measures.

We may evaluate information including:

Billing and shipping addresses
Address-verification results
Payment-authentication results
Device and browser information
IP address
Email address
Telephone number
Order value
Order history
Payment attempts
Delivery destination
Fraud-risk indicators
Previous returns, refunds, disputes, or confirmed misuse

Where reasonably necessary, we may ask you to:

Confirm order information
Confirm billing or shipping information
Confirm payment authorization
Respond by email or telephone
Complete authentication through your bank
Provide limited identifying information
Use another verifiable payment method

Do not send complete card numbers, card security codes, online-banking passwords, or digital-wallet passwords to MARSTEN.

Failure to provide reasonably requested verification may result in:

Processing delay
Order hold
Order restriction
Order cancellation
Refund to the original payment method

We may retain and disclose relevant transaction records to payment processors, banks, card networks, Shopify, carriers, professional advisers, regulators, or authorities where reasonably necessary to:

Verify payment authorization
Prevent or investigate fraud
Respond to a payment dispute
Comply with law
Protect legal rights

Personal information used for these purposes is handled as described in our Privacy Policy.

13. Shipping and Delivery

MARSTEN currently ships to eligible addresses within the United States, subject to the restrictions stated in our Shipping Policy.

Available shipping options, charges, handling periods, and estimated delivery periods are displayed through the website or checkout.

Processing and delivery dates are estimates unless we expressly state in writing that a date is guaranteed.

Orders may be fulfilled through third-party:

Warehouses
Suppliers
Fulfillment partners
Shipping carriers
Local delivery partners

An order containing multiple products may arrive in separate packages or on different dates.

Delivery may be affected by:

Carrier operations
Severe weather
Peak demand
Public holidays
Incorrect addresses
Building-access restrictions
Labor disruptions
Transportation interruptions
Product availability
Fraud or security verification
Events outside our reasonable control

If we cannot ship within the timeframe represented when the order was placed, we will provide the delay, consent, cancellation, or refund options required by applicable law.

A carrier delay after dispatch does not automatically cancel the order.

Complete shipping terms are available in our Shipping Policy.

14. Tracking and Delivery Evidence

After dispatch, available tracking information will generally be sent to the email address associated with the order.

Tracking may require time to begin showing movement after a label is created or a package is transferred to a carrier.

Delivery may be documented using available records including:

Tracking status
Delivery date and time
Carrier scans
Delivery photographs
Signature confirmation
GPS or location information made available by the carrier
Address confirmation
Reception, mailroom, locker, or access-point records
Communications from the carrier or recipient

A carrier’s delivery confirmation is evidence that the package was delivered to the address or authorized delivery location associated with the order.

It does not prevent you from contacting us about a genuine delivery concern and does not eliminate any right that cannot lawfully be excluded.

15. Lost, Missing, Stolen, or Misdelivered Packages

Tracking has not updated for an unusual period
A package appears lost in transit
Tracking states “delivered” but the package cannot be located
The package appears to have been delivered to an incorrect location

Before reporting a delivered package as missing, you should:

Check the delivery location and surrounding area.
Check with household members and neighbors.
Check with reception, mailroom, locker, or building-management personnel.
Review any delivery photograph or carrier notice.
Confirm that the shipping address provided with the order was correct.
Contact the carrier where requested.

We may request information reasonably necessary to investigate, including:

A signed non-receipt statement
Confirmation of the address
Completion of a carrier claim
Building-management confirmation
Available security-camera information
A police or incident report where theft or fraud is reasonably suspected
Limited identity verification

A confirmed-delivery claim is evaluated using the complete available evidence and does not automatically qualify for a refund or replacement.

Knowingly providing false information concerning delivery, theft, payment authorization, identity, or order receipt is prohibited.

Additional terms are provided in our Shipping Policy and Return and Refund Policy.

16. Order Changes and Cancellations

Submitting a request does not guarantee that the order can be changed or stopped.

A cancellation or modification may no longer be possible after an order:

Enters fulfillment
Is allocated to a warehouse
Is prepared or packed
Receives a shipping label
Is transferred to a carrier

A cancellation is effective only when confirmed by MARSTEN in writing.

If the order can no longer be cancelled, you may request a return after delivery in accordance with the Return and Refund Policy.

Refusing delivery does not automatically cancel an order or guarantee a refund.

Nothing in this section limits rights that apply where an order cannot be shipped within the represented timeframe or where cancellation is otherwise required by law.

17. Returns, Refunds, and Store Credit

Returns, refunds, replacements, and store credit are governed by our Return and Refund Policy, which is incorporated into these Terms.

MARSTEN provides a 90-calendar-day return-request period beginning on the date the carrier records the applicable product as delivered, subject to the complete eligibility conditions, exclusions, deadlines, and procedures in that policy.

Standard change-of-mind returns generally require that the product be:

Unused
Unassembled
Uninstalled
Unaltered
Complete
In original condition
Returned in original product packaging
Authorized before shipment

Return authorization does not guarantee a refund. Returned products may be inspected to verify:

Product identity
Serial number or identifying information
Condition
Completeness
Signs of use
Assembly or installation
Alteration
Contamination
Missing components
Compliance with return instructions

Standard eligible refunds are generally issued to the original payment method after the return and inspection requirements have been satisfied.

Products that are used, opened, hygiene-sensitive, incomplete, damaged after delivery, or otherwise ineligible are not automatically entitled to a refund.

In limited circumstances, MARSTEN may voluntarily offer partial or full store credit as a discretionary goodwill resolution.

Store credit:

Is not guaranteed
Must be confirmed in writing
May be subject to written conditions
Has no cash value except where required by law
Cannot be combined with a duplicate refund, replacement, payment reversal, or chargeback recovery for the same product or loss

Complete terms are available in our Return and Refund Policy.

18. Damaged, Defective, Incorrect, or Incomplete Products

Inspect your order promptly after delivery.

Arrives damaged
Appears defective
Is materially different from the product ordered
Is missing a confirmed component

We may reasonably request:

Photographs or video
A description of the issue
Packaging photographs
A photograph of the shipping label
Serial, batch, barcode, or product-label information
Troubleshooting results
Return of the product for inspection

You agree to provide accurate information and reasonably cooperate with the assessment process.

Do not discard, repair, alter, dismantle, return, or dispose of the product, packaging, labels, or included components while the matter is under review unless instructed by MARSTEN.

Depending on the circumstances and applicable law, a resolution may include:

Troubleshooting
Replacement parts
Replacement product
Return authorization
Partial refund accepted by the customer
Full refund
Store credit accepted by the customer
Another mutually agreed resolution

We may require the product to be returned before issuing a replacement or refund.

These provisions do not limit any non-waivable right or remedy applicable to a defective, unsafe, or materially misdescribed product.

19. Payment Disputes and Chargebacks

We encourage you to contact us about an order, delivery, product, return, or refund concern before opening a payment dispute so that we have an opportunity to investigate and provide an appropriate resolution.

Nothing in these Terms prevents you from exercising a legitimate right through your bank, card issuer, payment provider, regulator, consumer-protection authority, or court.

However, you must not knowingly submit:

A false or misleading payment dispute
A claim that an authorized transaction was unauthorized
A non-receipt claim after receiving the order
A duplicate-refund claim
A claim that deliberately omits material delivery, replacement, return, refund, store-credit, or communication records

If a payment dispute is opened, we may provide the payment provider with information relevant to the transaction, including:

Order confirmation
Checkout and payment records
Billing and shipping information
Fraud-screening results
Customer communications
Product-page records
Applicable policy records
Tracking and delivery evidence
Delivery photographs or signatures
Return and inspection records
Refund, replacement, or store-credit records
Relevant account or website activity where lawful

While the same funds are subject to an active chargeback, payment dispute, reversal, or payment hold:

We may be technically or procedurally unable to issue a separate refund.
A pending refund or store credit may be paused.
The resolution may need to proceed through the payment provider’s dispute process.
Existing instructions concerning preservation or return of the merchandise may remain applicable.

Opening a dispute does not create a right to receive or retain more than one financial recovery for the same product or loss.

Duplicate recovery may include:

A merchant refund and successful chargeback
Store credit and a chargeback recovery for the same loss
A replacement and full refund
Reimbursements from multiple protection providers
Retaining both the merchandise and reversed payment where payment or return remains lawfully required

If duplicate reimbursement occurs, you must notify MARSTEN and reasonably cooperate in correcting it.

Where a dispute is resolved in MARSTEN’s favor, the original transaction remains payable and valid.

Where a dispute is resolved in the customer’s favor, further handling of the merchandise will be determined by:

Applicable law
The payment provider’s decision
The condition and location of the product
MARSTEN’s written instructions

We may restrict future purchases associated with confirmed fraud, abusive disputes, repeated policy misuse, or unpaid amounts, to the extent permitted by law.

20. Personal and Household Use

Unless expressly agreed otherwise in writing, MARSTEN products are sold for personal and household use.

You may not purchase or use products for:

Unauthorized resale
Commercial distribution
Unlawful export
Reverse engineering
Counterfeiting
Fraudulent or deceptive conduct
Use contrary to product instructions
Use prohibited by applicable law

We may limit quantities, verify the purpose of an order, decline an order, or cancel a purchase that reasonably appears intended for unauthorized resale or commercial distribution.

These Terms and contracts formed through the Services are governed by the laws of the Hong Kong Special Administrative Region, without regard to conflict-of-law principles.

To the extent permitted by law, disputes that cannot be resolved informally may be submitted to a court of competent jurisdiction in Hong Kong.

However, this provision does not deprive a consumer of:

Mandatory protections available under the laws of the consumer’s jurisdiction
A right to bring a claim in another forum where that right cannot lawfully be waived
A right to contact a regulator or consumer-protection authority
A right to exercise a legitimate remedy through a payment provider
A right to seek urgent or injunctive relief

Before beginning formal proceedings, we encourage you to contact us at contact@marstenhome.com so that we can review the matter and attempt to resolve it.

Please provide:

Your full name
Order number
Contact information
A clear description of the concern
The resolution requested
Relevant supporting information

We will review submitted concerns in good faith.

34. Severability

If any provision of these Terms is held unlawful, invalid, or unenforceable, that provision will be:

Enforced to the maximum extent permitted; or
Severed where necessary

The remaining provisions will continue in effect.

35. No Waiver

A failure or delay by MARSTEN in enforcing a provision does not waive:

That provision
A later breach
Any other right

A waiver is effective only when expressly confirmed in writing by an authorized representative of ZENTARA BRANDS LIMITED.

36. Assignment

You may not transfer or assign your rights or obligations under these Terms without our prior written consent.

We may transfer or assign these Terms in connection with:

A merger
Corporate reorganization
Financing
Sale of assets
Transfer of the business
Transfer to an affiliated company

Any assignment will remain subject to applicable consumer rights.

37. Entire Agreement and Policy Priority

These Terms and the policies incorporated by reference constitute the agreement between you and MARSTEN concerning the Services and replace prior communications concerning the same subject matter.

Product-specific written terms, warnings, instructions, and warranty information form part of the agreement for the applicable product.

Where the documents address the same matter:

The Shipping Policy controls shipping and delivery procedures.
The Return and Refund Policy controls return eligibility, refunds, replacements, and store credit.
The Payment Policy controls payment processing and billing procedures.
The Privacy Policy controls personal-information practices.
Product-specific written terms control the particular product where they are more specific.
These Terms control general contractual matters.

If any policy conflicts with a mandatory legal requirement, the mandatory requirement applies.

We may update these Terms to reflect changes to:

The Services
Business operations

Legal or regulatory requirements

The current version will be posted on this page with a revised “Last Updated” date.

Changes apply prospectively from publication unless applicable law requires additional notice or consent.

The version in effect when an order was submitted will generally govern that order, except where:

A later change is required by law
The parties agree otherwise
The later version is more favorable to the customer
