This product is a custom-made item and requires the buyer to provide design drafts such as text or pictures. The clarity of the pictures directly affects the quality of the product; the clearer the pictures provided, the better the product quality. The quotation can only be provided based on the specific materials/specifications/quantities and packaging requirements of the customer's products. This product customization does not support returns. If the quantity is large, the seller will ask the buyer to make a sample first. The seller will only deliver the bulk goods after the buyer confirms the sample. If you have any other questions, please contact customer service.
