Made from chic floral Oshima Tsumugi silk (from the fabric purchase description). The inside is blue-gray kimono lining fabric. Each has interfacing applied. The chic colors and large floral pattern are elegant. Height: 23cm, Width: 15cm 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 colors may appear different depending on your device.
