25.5cm × 25.5cm Mounting paper / 20 sheets (40 pages) Stickers / 4 sheets The cover is thick and firm, but the mounting paper inside is not as thick as drawing paper. Both books have been stored at home for a long time, so there are some stains on the inside of the front and back covers, and on the last page of the mounting paper, as shown in photos 9 and 10. Please consider this if you are not too concerned about minor details. This is a scrapbook that can be used to paste photos, draw pictures, and write messages with the included stickers. You can also have fun making travel journals, etc. Calendar/Schedule design: Character #HelloKitty #PhotoAlbum #Album #MessageBook #AutographCard
