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 21cm tall, 15cm wide, and about 2.5cm thick (see image 6). The front is a combination of three types of Kurume-ori fabric. The plain cover is a dark gray. Image 3 is the closest color. The back is indigo Kishu Hosofu. Interfacing is applied. Height: Approximately 22cm Width: Approximately 39cm when opened No bookmark string is attached. Although carefully finished, this is handmade by an amateur. Thank you for your understanding. I hope someone who doesn't mind the small details will use it daily.
