Made from a tsumugi silk fabric. It has a smooth, soft feel. This is a very fine tsumugi item. It has a sheen, so the color appears darker or lighter depending on the angle. It makes the characteristic squeaky sound of tsumugi. There are no seams. The lining is new cotton fabric. It's a cute light blue color. This is handmade by my mother, who used to work as a dressmaker. Please note that it is thinner than commercially available items. I have other items for sale, so please take a look. Thank you. #Maru-bukuro (round bag) #17-string koto #Shamisen
