Made from a cute floral Oshima Tsumugi (from the fabric purchase description). The inside is kimono lining fabric. Interfacing is applied to each. Height: 23cm, Width: 16cm No gusset Shoulder strap: 110cm (length not adjustable, commercially available) I think it's easy to use because it has pockets inside and out. Please refrain from purchasing if you are concerned about seams or slight misalignments. Please note that the color may differ depending on the device you are using.
