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 surface where stickers are applied, initial scratches on the sheets used, and some irregularities. Please understand this. There is no problem with use, but please refrain from purchasing if you are looking for a perfect product. Due to the nature of the sheets, dust tends to stick very easily. We try to remove it as much as possible, but it cannot be completely removed, so please understand. The material is different from commercially available sticker release paper. If you apply paper stickers, they may be difficult to remove or may not come off at all. Price revised due to rising material costs. Please note. Please purchase only if you understand everything above.
