This is a book cover for A5 size books. This size is common for literary magazines like Bungeishunju and reference books. For reference, the book used in the photos is approximately 21cm tall, 15cm wide, and 2.5cm thick (see image 6). The front uses Enshu cotton and Kurume-ori fabric. The back is dark navy Kurume-ori. Interfacing is applied. Height: Approximately 22cm Width: Approximately 39cm when opened No bookmark string is attached. It is carefully finished, but it is handmade by an amateur. Thank you for your understanding. I hope someone who doesn't mind the small details will use it daily.
