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 (image 6). The front is a combination of two types of Kurume-ori and Enshu cotton. The plain cover is a dark blue-gray. The color in image 7 is close. The back is Kishu Hosofu in deep green. 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. I hope you understand this, and that those who don't mind the small details will use it for everyday purposes.
