Made from Oshima Tsumugi (based on the fabric purchase information). The inside is made of yellow-ocher obi lining fabric, and interfacing is applied to both. I think it's easy to use because it has pockets inside and out. Height: 23cm, Width: 15.5cm Shoulder strap: 110cm (Length cannot be adjusted, commercially available) Please refrain from purchasing if you are concerned about seams or slight misalignments. *Please note that the color may differ depending on your device.*
