Wunder Kassette

Returns are accepted only for items with manufacturing defects (damaged upon receipt) reported within one week of receiving the product.

For most items (see exceptions below), malfunctions occurring within one week of receipt will be repaired or exchanged free of charge.

Please check the condition of your item as soon as possible after receiving it. We recommend wearing it for even a short time within the first few hours.

Natural breakage during use within one week of receipt is also considered a manufacturing defect.

We will cover all shipping costs.

1. Please let us know about the issue via message. (Contact us through the inquiry form or via DM on SNS — X or Instagram.)
2. We will send you a return envelope, bubble wrap, and a Click Post shipping label. ※ We will use the address from your original order by default.
3. Place the item in the return envelope and drop it in a mailbox.
4. We will repair the item if possible, or prepare a new one if repair is not possible. ※ The replacement may differ slightly in shape or color from the original.
5. The repaired or replacement item will be sent back to you.

Once we receive your inquiry, we will check our parts inventory. We will ask you to return the item after confirming that the necessary parts are in hand. If parts are not immediately available, please allow at least 3 days. For overseas-imported parts, it may take approximately one month.

Once the item arrives with us, we will repair and ship it within approximately one week. ※ Excluding shop holidays such as year-end and New Year.

Repairs are still available after one week, but will be subject to a fee.

Damage or loss of one-of-a-kind parts cannot be handled through standard repair or exchange.

We will do our best to find a similar part if an approximate match is acceptable, but this may not always be possible.

For issues arising more than one week after receipt, or for damage caused by the customer, paid repairs are available.

Compensation for damage occurring during repair applies only to items purchased from our shop.

We will provide either a new copy of the same item or, if unavailable, a refund of half the item's price.

If you have made at least one purchase from our shop, we can also repair items purchased elsewhere.

However, we cannot provide damage compensation during repair for items from other shops.

Please also note that repairs may not always be possible, and replacement parts may differ slightly in color.
