Here's the professional translation of the purchase policy clauses:

1. We guarantee that every pair of shoes is authentic and handcrafted. If you receive counterfeit products, please provide certification from a relevant authentication institution, and we will offer three times compensation. If there are any quality issues, please contact us immediately.

2. Each product requires 1-7 days of custom production after your purchase. Shipping will only begin after production is completed. We appreciate your patience during this period. You may contact us for order status updates.

3. If there are no quality issues and you no longer wish to continue with the purchase for personal reasons, please be sure to contact us and submit a return request before the product is shipped. Otherwise, you will be responsible for the round-trip shipping costs.

4. If you find the size unsuitable after receiving the product, please contact us and return the item. We will exchange it for the correct size, but you will be responsible for the round-trip shipping costs.

5. Returns or exchanges are not supported if the product has been unsealed, worn, altered, damaged in appearance, or is in any imperfect condition.

6. To avoid unnecessary disputes regarding product quality, please record an unboxing video as evidence immediately upon receiving the product.

7. If you have any questions, please contact our customer support team. We will respond promptly.
