This is a book cover for a paperback (shinsho-ban) size book. The front has a floral pattern, and the inside has a polka dot pattern. The following sizes are compatible: Paperback (shinsho-bon) size: 18.2 cm tall, 10.3 cm wide BL novel paperback (shinsho) size: 18.2 cm tall, 11.5 cm wide Also, although there will be extra height, Comic book size (shonen manga, shojo manga): 17.6 cm tall, 11.3 cm wide, can be used if you don't mind the extra material. Paperback (shinsho-bon) size: 17.4 cm tall, 10.3 cm wide, can also be used in the same way. However, B6 size and A5 size books are not compatible. Photo 4 shows a paperback size book (only a BL novel is available, so it's photographed with a BL paperback), and photo 5 shows a comic book size. The cover size is approximately 19.5 cm tall and 32.5 cm wide. Adjustment is possible depending on the thickness of the book. Each one is carefully made, but it is handmade by an amateur (stitches and slight misalignments, etc.), so please understand that it is handmade. m(_ _)m I am also selling on other apps, so I will delete the listing if it sells.
