Made from Oshima Tsumugi fabric (from the description of the fabric purchase) that still has the training stitches. The inside is made of a reddish-brown lining fabric from the same kimono, and interfacing has been applied to both. I think it's easy to use because it has pockets inside and out. Height: 23cm Width: 16cm Shoulder strap: 110cm (Length cannot be adjusted, commercially available) Please refrain from purchasing if you are concerned about seams or slight misalignments. *The color may appear different depending on your device.*
