The material is silk tsumugi on both the front and back. It's sturdy. It has a lovely pattern of stacked bricks. Because of the unique weave, the back cannot be used. It will be a lined construction. The brick color has a gradation. Because it's a lined tote bag, it's sturdy and easy to use. Size: 37cm tall, 34cm wide. This includes a 3cm base gusset. There is a pocket inside. A drawstring bag is included. I think you'll be able to use it in a wonderful and fun way.
