This is a long bag for a medium-neck shamisen, a thin-neck shamisen, or a jiuta shamisen. It was made from fabric that was unpicked and washed from a never-worn "tsukesage" kimono. There are no stains and it is in beautiful condition. It's a satin-like fabric. The lining is unused white juban fabric with a floral pattern. Both the outer and inner fabrics are 100% silk. This is a handmade item created by an amateur as a hobby, so thank you for your understanding.
