These are waist cords made from a disassembled silk crepe de Chine nagajuban (long undergarment). They are 3.5 cm wide and 300 cm long, and there are 6 cords. These silk cords feel wonderful against the skin, with a pleasant silk-on-silk sound. Recommended for those with a 1-meter waist or those who are a bit more plump. Three cords for 1600 yen. Please note that there may be small holes or threads from the disassembly. I may have overlooked some stains. Please refrain from purchasing if you are concerned about these imperfections.
