This is an antique Nagoya obi. There are stains due to age. It has a soft texture. I believe it is pure silk. Total length: approximately 328 cm Thank you for reading. I started selling items because kimonos that would otherwise be discarded have come to me. (They were destined to be thrown away if I hadn't taken them in.) I am not an expert on kimonos. I am especially unable to determine the material. Please understand. I want to enjoy Mercari with kimono lovers. There are many kimonos at my physical store in Kita-ku, Okayama City. Please see my profile.
