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 uses two types of Kurume-ori fabric. The back is made of 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 minor imperfections will use it daily.
