The material is silk tsumugi. There are irregularities in the yarn, so there may be knots and imperfections. That gives it a simple, rustic charm. The yarn is a bit thick and has a firm texture. It has a nostalgic, everyday feel. It's a large size, so it's convenient and holds a lot. Size: 47cm long, 48cm wide. This includes a 6cm bottom 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. I think you can use it casually and enjoyably.
