This is a sanshin bag. It was made from a bolt of wool fabric for children's kimonos. It has a dyed-like pattern with vivid and cute colors. The wool fabric is thick and has a good stiffness. The opening is made wider than commercially available ones, so I think it will be easy to put the sanshin in. If you put the tenjin part on like a hood, it will fit without sticking out. The tenjin cap is just something you put on like a hat. Please think of it as a bonus. It's stuffed with cotton and is fluffy. This is a handmade item made by an amateur as a hobby, so thank you for your understanding.
