I received and stored these two used Nagoya obi. They have a retro feel and the embroidered otaiko (back of the obi) is gorgeous. The black one is particularly short, so it's suitable for petite and slender people. Although I don't see any noticeable large stains or dirt on either obi, they show signs of age, with some areas having scuffs and light soiling. They are recommended as materials for remaking or for practicing tying obi. How about using them for purposes where you don't have to worry about them?
