★ This is a new obi fabric repurposed. "Spacer cloth, buffer cloth." Size: Approximately 33cm wide x approximately 28cm long ★ There may be some slight variations. Please understand. ★ This is a handmade "spacer cloth, buffer cloth" to protect the dragon's spine of the koto. It is made of "pure silk." While it may vary from person to person, when storing the koto, the koto bridges are removed, and the "spacer cloth, buffer cloth" is used between the center of the dragon's spine and the strings. Previously, I used things like hand towels, but I decided to create "silk spacer cloth, buffer cloth" to make it look more elegant. "Silk" has excellent moisture absorption and release properties, regulating humidity, making it an excellent material for protecting the koto. How about it for your beloved koto? ★★★ Since this is handmade, there are variations in size. Please consider purchasing only if you understand this. If you are looking for perfection, please refrain from purchasing.
