These are koshihimo (waist cords) made from a new muslin nagajuban (long undergarment). They are 4 cm wide and 4 meters long, and there are two of them. Recommended for those with a 1-meter waist or those who are a bit plump. Please forgive any threads, etc., that may be on the fabric. There may be oversights such as stains. Please refrain from purchasing if you are concerned.
