This is a sticker refill made by processing double-sided release paper into an A7 size binder. Since you can stick stickers on both sides, you can store a lot of them. ・A7 6-hole refill 　Double-sided release paper for stickers × 20 sheets 　(Size: approx. 12.7cm long × 9.5cm wide) Because it uses release paper used for sticker backing, you can easily stick and peel off paper stickers and stickers. This refill is perfect for sticker swapping and sticker books! 【Options】 When my daughter comes home from sticker swapping, she sometimes drops stickers, so I made a backing cover for the sticker book. When swapping stickers, you can flip open the cover without removing it from the binder, and when you're done, just snap the cover closed (no need to remove the binder when putting it back). Those who don't want to flip the cover can insert and remove the backing from the top to swap stickers. Both options also prevent stickers from getting dirty. [Option ①] Since the cover can be flipped open, it does not completely prevent stickers from falling out. It can prevent stickers from getting dirty. If the stickers are quite thick, they may lift up and the slits may open on their own. [Option ②] Because it is in a bag shape, it prevents stickers from falling out. It also prevents dirt. Since the whole thing bulges when you put thick stickers in, the sticker backing inside is made slightly smaller. The lift varies depending on the thickness of the stickers, so if the backing sticks out of the binder because it doesn't go all the way in, please cut it to size yourself. Option ①…3 sheets for an additional 200 yen (cover only) Option ②…3 sheets for an additional 250 yen (cover and backing) 【Requests】 ・I've tried it with various stickers, and some stickers peel off easily and some stick firmly depending on the type and manufacturer. Please try it little by little. ・Since it is handmade from cutting to hole punching, there may be some slight deviations. Please understand this before purchasing. ・Fine dust and dirt may be mixed in during the release processing. Please understand. ・Binders and stickers are not included.
