This is a bag for an Okinawan sanshin. It's made of thick, high-quality silk紬 fabric. The fabric is woven with black, navy, and white threads, and the lining has the same pattern. The pattern, which looks like yachts and Western-style houses, is cute. The opening is wider than commercially available ones, so it should be easier to put the sanshin in. As shown in the last image, you can store the sanshin without it sticking out by putting the tenjin (headstock) in like a hood. Approximate measurements when laid flat: 88 x 29 cm This is a handmade item created by an amateur as a hobby, so thank you for your understanding.
