Thank you for viewing! This is a men's obi (sash). The material is unknown, but I think it's probably cotton. It's a sturdy weave and seems durable, with a very comfortable feel when tied. It's navy blue and reversible, so I think it can be widely used with men's yukata and kimono. It can still be worn, but it also seems like it would be great material for remaking into Japanese-style accessories. 【Condition】 There is a weave flaw (1 spot) and light stains (3 spots) on the front. There is discoloration (2 spots) on the back. I think it's at a level that doesn't affect wear, but please check the photos. Home-cared. 【Color】 Base color: Navy Reversible front and back. 【Material】 Unknown (probably cotton) 【Size】 Width: 9cm Length: Approximately 370cm Since the material is unknown, I may not be able to provide satisfactory answers to your questions, but I will do my best to answer based on what I can tell from looking at the actual item. Thank you for your consideration, and I appreciate your understanding of this being a used item.
