Return and Refund Policy
Last updated: September 15, 2026
Thank you for shopping with Butterberg ApS through wyumi.shop.
This Return and Refund Policy explains the conditions for returns, withdrawals, damaged or incorrect products, and refunds.
Nothing in this Policy is intended to limit any mandatory consumer rights available under applicable law.
1. 30-Day Voluntary Return Policy
In addition to any statutory rights that may apply, we provide a 30-day voluntary return period for eligible products.
You may request an eligible voluntary return within 30 days after receiving your order.
To qualify for a voluntary return, the product should generally:
- Be in the condition in which it was received;
- Be unused and undamaged;
- Include supplied accessories and components;
- Include the original packaging where reasonably possible; and
- Be accompanied by proof of purchase.
To request a return, please contact us before sending the product back.
Email: support@wyumi.shop
We will provide the applicable return instructions.
2. EU/EEA Statutory Right of Withdrawal
Where applicable, consumers in the European Union and European Economic Area generally have the right to withdraw from an eligible distance purchase within 14 days without giving a reason, subject to applicable legal exceptions.
The withdrawal period generally begins on the day on which you, or a third party designated by you other than the carrier, receives the goods.
To exercise your right of withdrawal, you must inform us of your decision to withdraw from the purchase through a clear statement before the applicable withdrawal period expires.
You may contact us at:
Email: support@wyumi.shop
The statutory right of withdrawal is separate from our additional 30-day voluntary return policy.
Nothing in our voluntary return policy reduces any mandatory statutory withdrawal rights.
3. How to Request a Return
Before returning a product, please contact us at:
Please provide, where applicable:
- Your full name;
- Order number;
- Email address used for the order;
- Product you wish to return; and
- Reason for the return.
Photographs or videos may also be requested where reasonably necessary to evaluate a damaged, defective, incorrect or incomplete product.
After receiving your request, we will provide the applicable return instructions.
Do not automatically send a return to our registered company address unless that address is specifically confirmed in the return instructions.
The appropriate return destination may depend on the product, order and return circumstances.
4. Return Condition
For returns made under our voluntary 30-day return policy, returned products should generally be:
- Unused;
- Undamaged;
- In the condition in which they were received;
- Complete with supplied components and accessories; and
- Returned with the original packaging where reasonably possible.
Customers may be responsible for any reduction in value caused by handling beyond what is reasonably necessary to establish the nature, characteristics and functioning of the goods, where permitted by applicable law.
These voluntary return conditions do not limit mandatory rights relating to defective, damaged, incorrect or non-conforming goods.
5. Damaged Products
Please inspect your order after delivery.
If a product arrives damaged, contact us as soon as reasonably possible at:
Please provide, where applicable:
- Your order number;
- Description of the damage;
- Photographs of the outer packaging;
- Photograph of the shipping label;
- Photographs of the damaged product; and
- Video showing the issue where reasonably necessary.
Please retain the product and packaging while the matter is being reviewed where reasonably possible.
After reviewing the available information, we will provide an appropriate remedy in accordance with the circumstances and applicable consumer law.
6. Incorrect Products
If you receive a product different from the product you ordered, please contact:
Please provide:
- Your order number;
- Description of the issue;
- Photographs of the product received; and
- Photograph of the shipping label where relevant.
After reviewing the information, we will provide an appropriate solution, which may include a replacement, return or refund depending on the circumstances.
7. Missing Products or Components
If a product or component is missing from your order, please contact:
Please provide:
- Your order number;
- Details of the missing product or component; and
- Relevant photographs where appropriate.
We will review the available information and provide an appropriate solution.
8. Defective or Non-Conforming Products
If you believe that a product is defective or does not conform to the order, please contact us at:
Please provide your order number and a description of the problem.
Photographs or videos may be requested where reasonably necessary to evaluate the issue.
Mandatory consumer rights relating to defective or non-conforming goods remain unaffected by our voluntary return policy.
9. Return Shipping Costs
For an ordinary change-of-mind return under our voluntary 30-day return policy, the customer is generally responsible for the direct cost of returning the product.
For an applicable EU/EEA statutory withdrawal, the customer may be responsible for the direct cost of returning the goods where this responsibility has been properly disclosed and permitted by applicable law.
Customers will not normally be responsible for reasonable return shipping costs where the return results from a confirmed issue attributable to us, such as:
- A defective product;
- A product damaged during delivery;
- An incorrect product; or
- Missing components.
Where we are responsible for the return cost, please follow the return instructions provided by our customer service team.
Do not send a parcel using an unauthorized premium or express return service and assume that all resulting costs will automatically be reimbursed.
10. Return Address
Please contact us before returning any product.
Email: support@wyumi.shop
We will provide the applicable return instructions and return destination.
Our registered company address should not automatically be used as a return address unless we specifically confirm it for your return.
This helps ensure that returned products are sent to the location appropriate for processing the applicable return.
11. Return Inspection
After a returned product is received, it may be inspected to confirm:
- The identity of the returned product;
- Its condition;
- Whether supplied components are included; and
- Whether the return meets the applicable return conditions.
We will inform you if additional information is reasonably required.
Mandatory statutory rights are not dependent on voluntary return conditions where applicable law provides otherwise.
12. Refunds
Where a refund is approved, we will process it in accordance with the applicable return or statutory rights.
For eligible voluntary returns, after the returned product has been received, inspected and approved, we will normally initiate the refund within:
10 business days after approval.
Where mandatory consumer law requires a different refund deadline or procedure, the applicable mandatory law will prevail.
13. Cash on Delivery (COD) Refunds
Orders placed through our store may be paid using Cash on Delivery (COD) where this option is available during checkout.
Because COD payments are collected through the delivery process, an approved refund cannot always be returned automatically through the original payment method.
Where a refund is approved for a COD order, we may contact you to arrange an appropriate refund method.
We may request information reasonably necessary to process the refund.
For security reasons, please never send:
- Passwords;
- PIN codes;
- Account login credentials; or
- Other unnecessary sensitive credentials
by email.
14. Shipping Charges and Statutory Withdrawal
Where an eligible EU/EEA consumer validly exercises an applicable statutory right of withdrawal, reimbursement of standard delivery costs will be handled in accordance with applicable consumer law.
If you selected a delivery method that was more expensive than the least expensive standard delivery option offered for the order, the additional delivery cost may not be refundable where permitted by applicable law.
For voluntary returns outside an applicable statutory withdrawal right, shipping-charge refunds will depend on the circumstances and the conditions of the voluntary return policy.
15. Refused or Uncollected Parcels
If you no longer wish to receive an order, please contact us as soon as possible rather than simply refusing delivery.
Where a parcel is returned because:
- It was not collected;
- An incorrect or incomplete delivery address was provided; or
- Delivery was refused,
the handling of any resulting return costs, reshipping costs or refund will depend on the circumstances and applicable law.
Nothing in this section limits mandatory statutory withdrawal or consumer rights.
16. Sale or Promotional Products
Products purchased during a sale or promotion remain subject to mandatory consumer rights.
Eligibility for our additional voluntary 30-day return policy may depend on the applicable product and return conditions.
Any restriction relating to a voluntary return does not remove mandatory rights that may apply to:
- Defective goods;
- Damaged goods;
- Incorrect goods;
- Non-conforming goods; or
- Applicable statutory withdrawal rights.
17. Exchanges
If you wish to exchange a product, please contact us at:
Whether a direct exchange is available may depend on the product and stock availability.
Where a direct exchange is not available, we may provide appropriate return instructions and explain the available options.
18. Order Cancellation
If you wish to cancel an order before dispatch, please contact us as soon as possible:
We will make reasonable efforts to assist.
Once an order has already entered processing or has been dispatched, cancellation before delivery may no longer be possible.
This does not limit any statutory withdrawal or cancellation rights available under applicable law.
19. Proof of Purchase
We may reasonably request information necessary to identify your purchase, such as:
- Order number;
- Customer name;
- Email address used for the order; or
- Order confirmation.
Please do not send unnecessary sensitive payment or account credentials.
20. Mandatory Consumer Rights
Nothing in this Return and Refund Policy is intended to exclude, restrict or reduce any mandatory consumer right that cannot legally be excluded.
Where applicable consumer law provides greater protection than this Policy, the applicable mandatory law will prevail.
21. Changes to This Policy
We may update this Return and Refund Policy where reasonably necessary to reflect changes in our return procedures, delivery arrangements, business operations or applicable legal requirements.
The current version will be published through our online store.
Changes will not retroactively reduce mandatory rights relating to purchases already completed.
