I purchased this last year on Amazon, but I never had a chance to use it, so it has been stored at home. Therefore, although it is unused, please understand that it has been opened once and may have slight wrinkles or stains due to storage. For detailed specifications, please search on Amazon for "Sublimation Shrink Wrap Sleeves 20 pieces" to find the product for sale. You can check the details there. ※Currently, only the "13cm x 26cm" size is listed on Amazon. Although the size is different, the contents are the same. Size: 15cm x 29cm Material: PET material Quantity: 20 sheets Application: Applicable to both flat and curved items such as mugs, tumblers, cups, and water bottles. Amazon selling price: 1,160 yen Thank you.
