Backalleve A unique back support belt that offers much, much more than the competition. Our dual-belt construction and us-patented lower back strip (we call it "the bone") keep backalleve firmly in place to avoid annoying slippage that comes with other belts on the market. We use all-natural cotton and natural rubber that allow the user to wear backalleve 24 hours a day comfortably, even when playing light sports such as golf, jogging, or bicycling. Already more than 150, 000 belts sold in Japan. 50 units/box (cardboard box) 15kg 28 inch(70cm) x17 inch(43cm) x 14 inch(35cm)
