Please choose the size by yourself. If the size is not suitable for return or exchange, please bear the round-trip shipping cost by yourself! Wholesale is at a low profit margin. For orders greater than 3 but less than 10, only 15% can be returned or exchanged. Please place an order for 1 or 2 pieces for sample viewing before bulk purchase. If the sample viewing does not affect the secondary sales, you can bear the shipping cost for return or exchange at your own expense. Bulk purchase does not accept returns. Placing an order indicates your agreement. Thank you for your understanding.
