【Share with Friends at School or Cafes】 Sort by genre, so you can quickly find the stickers you want, making exchanges a breeze. Enjoy the "sticker exchange" and "deco-katsu" trends currently popular on social media, such as having fun with friends during breaks or taking photos with your favorite notebooks at cafes. 【Includes 10 double-sided, 2-pocket refills (split top and bottom)】 Storage guideline is within 2 pockets, 6cm wide x 6.9cm long. You can neatly sort cut purikura photos, flake stickers, character stickers, puffy 3D stickers, and small deco labels for dates and to-dos. It's convenient to quickly open the desired page when exchanging stickers with friends. Furthermore, you can neatly organize DIY-cut photos and handmade stickers, expanding your usage depending on your ideas. *Business cards (91 x 55mm) and standard trading cards (63 x 88mm) cannot be stored. 【High-Transparency PVC Cover】 Ultra-high transparency cover made of premium PVC material. 36% more transparent than standard products, making colors and patterns appear vivid, and allowing you to enjoy "display-like storage" the moment you open it. 【A7 size that fits in the palm of your hand】 Compact enough to fit easily into a mini bag or school bag pocket. You can easily use it on the go, such as showing stickers to friends during class breaks or at cafes after school, or quickly inserting small tickets collected during travel. It's small but sturdy, so you can carry it with you every day with peace of mind. 【Expandability to add pages freely】 Not only the included 10 refills, but also compatible with commercially available A7 (6-hole / 19mm pitch) standard refills. For example, if you add pages for each theme, such as "sticker only," "purikura only," and "travel ticket only," your collection will grow and grow. You can add memories every time you attend an event, and enjoy it for a long time as your own "growing sticker book."
