Control bands made of natural rubber, used in chiropractic. I purchased these about 3-4 years ago, but they are unused and the tubes are still held together with rubber bands. The bag has been opened, and the packaging paper shows noticeable tears and folds. The rubber feels like it could still be used normally, but the extent of aging is unknown. Selling price: 9,000 yen (9,900 yen including tax) #BodyControlBand #Chiropractic #Health #Beauty
