Warranty & Return Policy

7-Day Return Policy

On the ground of disliking a product, you may return any non-customized and non-sales product that is sealed, within the 7 days of receiving it. To be eligible for a return, your item must be unused and in the same condition that you received it. It also must be in the original packaging. Customized and sales products, accessories, or spare parts are excluded from the 7-day return policy. The shipping fee, handling fees, or any form of tax caused by the return will NOT be refunded.

Additionally, a restocking fee (35% of the item’s retail value) will be charged under this circumstance. This also applies to packages that have been opened but are still working well. Please contact to process your request. After receiving and checking that the item is in good condition, you will receive an email notifying you that the remaining 65% of the amount paid will be reimbursed directly to the payment method used (PayPal or Credit Card) within 3-5 working days. Please also note that PayPal or your bank may also require some processing time after we have issued your refund.

For items that are damaged, incorrect, or faulty upon delivery, you must contact within 7 days of delivery. You need to provide any solid proof of the problem you come across. YUNZII will help you identify the problem, and may cover the shipping cost according to the agreed amount. Please kindly note that a shipping fee that is extremely higher than 15% of product value is non-refundable. The shipping fee won’t be refunded if the product is not with any manufacturer defects.


All customized products (including customized keycaps) are non-refundable and cannot be returned to YUNZII. This also applies to items such as carry cases, cables, spare keycaps, switch pullers, and other accessories, due to hygiene purposes.

If one of the items in the package is defective/incorrect/missing (e.g. keycaps, cables, switch puller, etc.), a refund or replacement will be done only for that particular item, depending on the particular situation.


YUNZII offers a 1-year warranty for keyboards and DIY kits and offers a 6-month warranty for keycap sets and cases (e.g the case-only product sold separately). Batteries will be covered by the 3-month warranty. Accessories such as keycap pullers, switch pullers, free spare keycaps, cables, etc., are excluded from the warranty.
