This is a sticker album that I used about 10 to 15 years ago. It has many stickers pasted in it, such as puffy stickers, shaker stickers, water stickers, marble stickers, and 3D stickers. The Kiki & Lala and Hello Kitty stickers were mostly purchased at official Sanrio shops. Some stickers may have lost their adhesion. Also, some of the shaker stickers and water stickers have been glued in. Thank you for your understanding regarding long-term storage.
