This is a zippered binder pocket compatible with 6-hole binders. I bought these to store stickers that I couldn't or didn't want to stick to a sheet, such as those from sticker exchanges, but I have a lot left over, so I'm selling them. 《Set Contents》 Quantity: 2 sheets Size: Please check the photos 《Additional sheets available》 1 sheet ¥100 Please comment before purchasing if you would like to add more.
