This item is made of fabric, yet has a sturdy construction. The inside is burgundy, and the purple color on the surface is more subdued than in the image. How about using it to store white socks for the tea ceremony or to organize small items? It is unused, and there are fold lines in the middle. Size: Opening: 12 cm, Widest part of the bottom: 16 cm Length: 18 cm, Length of the bag portion: 14 cm The material is unknown, but I think it might be polyester.
