I made koshihimo (waist cords) from unused, long-term stored fabric (muslin, 100% wool). Width: 4cm, Length: 210cm. There are no seams. Please allow for slight variations. To keep shipping costs low, I will send it via regular mail (定形外郵便). I also have koshihimo that are 170cm long, suitable for children or slender individuals. Please take a look. Thank you.
