Thank you for viewing! Beautiful item! It was stored in a paulownia chest at my parents' house. Personally, I don't see any signs of use. Looking at the threads, it seems to be genuine silk. It's a very beautiful and sturdy obi (sash). The reversible, double-sided woven pattern gives it a luxurious feel. The colors are lovely and have a sheen. Obi length and width: 400 x 9.5 Please understand that there may be oversights and errors due to amateur inspection. I hope that those who understand that this is a used item will purchase it. No returns or refunds after purchase. Using anonymous Mercari shipping.
