This is a book cover for a Japanese B6-size book. The B6 size is 18.8 cm tall and 12.8 cm wide. Books larger than this size will not fit. *Hardcover books will not fit. The front has a scallop pattern, and the back has a polka dot pattern. The size is approximately 20.3 cm tall and 35.3 cm wide. Adjustment is possible depending on the thickness of the book. Each one is made carefully, but it is handmade by an amateur (stitches and slight misalignments, etc.), so please understand this is handmade. m(_ _)m I am also selling on other apps, so I will delete the listing if it sells.
