The material is silk tsumugi. The tsumugi itself is sturdy. The gradation creates movement within the simple design. It's a large size, so it's spacious and convenient. Size: 49cm tall, 48cm wide. Includes a 6cm base gusset. The straps are 3cm wide and about 60cm long. It can be worn over the shoulder. There is a pocket inside. A drawstring bag is included.
