About Return & Exchange

Update Date: October 6, 2026

Returns and Exchanges

Taiwan Orders

Except for products legally excluded from the seven-day right of rescission and clearly notified as such before purchase, you may return products or provide written notice to rescind the contract within 7 days starting from the day after receipt (including weekends and national holidays) without providing a reason. The cooling-off period is not a trial period; necessary unboxing or inspection will not, on its own, be grounds for refusing a return. Usage beyond necessary inspection, damage, or missing components will be handled according to law.

Application Process

  1. Within the time limit, send an email to missu21.co@gmail.com to express your intent to return.
  2. Provide the order number, name, contact information, and product details.
  3. Customer service will arrange for pickup or provide the return address and shipping method.
  4. Pack securely and include all original accessories and accompanying items.

A valid notice does not lose its effect while waiting for a response or approval from customer service. In general, a seven-day return does not require a reason, photos, or unboxing videos. By law, no return shipping fees, refund processing fees, or bank transfer charges are collected for seven-day returns.

Exchanges and Product Issues

For standard size or color exchanges, please place a new order after returning the item; the price, inventory, and delivery fees of the new order will be based on information at the time of placing the order. For defects, shipping damage, or incorrect items, please contact customer service as soon as possible with photos and order information; the company will cover necessary return shipping fees. If a replacement is unavailable, we will assist with a refund. Keeping an unboxing video is recommended, but failure to provide one will not be the sole reason for rejection. Statutory rights regarding defects do not automatically expire after the seven-day period.

Customized Lenses

Lenses produced according to personal prescriptions or specific requirements that meet legal criteria for exclusion from the right of rescission will have such limitations disclosed on the product page and before checkout; your rights regarding defects or production errors inconsistent with the order remain unaffected. General pre-orders do not waive the seven-day right due to the nature of pre-ordering, and non-customized items in the same order are not collectively excluded.

Overseas Orders

For general non-customized products, notify us of a return via email within 14 days starting from the day after receipt, and ship back within 14 days of the notice; customer service will provide the return address. Notice does not require prior approval. Return shipping fees for non-defective items are borne by the customer, as notified before purchase; shipping fees for defects, damage, or incorrect items are borne by the company. Necessary inspection will not be grounds for refusal based on unboxing. If applicable law provides more favorable rights or custom restrictions, those laws shall prevail.

Refund Methods and Timing

For Taiwan, refunds will be processed within 7 working days from the day after the returned item is received; according to the statutory seven-day right of rescission, the refund will be processed no later than 15 days from the day after receipt of the return. Overseas returns are handled according to applicable legal deadlines; where no mandatory provision exists, they will be processed within 7 working days from the day after receipt of the return; if the law requires calculations starting from the notification date, the time will not be extended based on receipt rules. The original shipping fee that must be refunded by law will be returned together.

  • Credit card refunds will be issued to the original card used; posting time depends on the bank.
  • ATM refunds will be issued to the customer's personal bank account.
  • PayPal refunds will be processed through the original transaction.

By law, no additional processing or bank transfer fees will be charged for refunds, and funds will not be converted to store credit without consent.
