Each one is made by hand, so there may be variations in size and hole position, unevenness in the cut edges of the holes and sides, scratches on the sticker application surface, initial scratches on the sheets used, and some irregularities. We appreciate your understanding. Due to the nature of the sheets, dust tends to adhere easily. We try our best to remove it, but it is not possible to remove it completely. Thank you for your understanding. The material is different from commercially available sticker release paper. When applying paper stickers, they may be difficult to remove or may not come off at all. Please purchase only if you understand everything above.
