This is a sticker album that I used about 10 to 15 years ago. It has many stickers, such as puffy stickers, shaker stickers, marble stickers, and 3D stickers. The My Melody, Little Twin Stars, and Hello Kitty stickers were mostly purchased at official Sanrio shops. Many of the stickers are quite thick. Some stickers may have lost their stickiness. Thank you for your understanding of long-term storage.
