For orders above the free shipping line, free shipping items, and shipping during shipping campaigns, we will bear the shipping fee as a service to the customer who made the purchase. When returning or exchanging an item for personal reasons, if the price of the item falls below the free shipping line, or if the item is returned or exchanged during a free shipping campaign or during a shipping campaign, the actual round-trip shipping cost will be borne by the customer. Thank you for your understanding.
