The material is silk tsumugi. It's a tightly woven fabric made of thin threads. You can hear the rustling sound of silk. The eco-bag has been made a bit larger, and the straps are long enough to be worn over the shoulder. How about using it as a slightly larger supplementary bag? Size: 40cm tall, 38cm wide The bottom is not gathered. The bottom can be gathered if you wish. The straps are about 3cm wide and 60cm long. There is a pocket inside. A drawstring bag is included. I think you will be able to use it gently and enjoyably.
