The stickers are filed using two A7 release papers side by side! I originally used these myself, so please refrain from purchasing if you are concerned about fine dust or scratches. The file itself has also been used by me several times. There are no noticeable scratches or stains. As shown in the photos, I also have paper items, postcards, and bags filed, and I will give them to someone who likes them ★★ I will also give away 5 Stitch Bonbon Drop mini stickers and 5 Npomchamu Puku Puku stickers together! ^_^
