C-PRIME BURN Series 361 M size ICE BLUE This is a series of silicone rubber sports bracelets that are easy to put on and take off because they have no buckle. They are popular with both men and women. C-PRIME is a California-born bracelet that combines fashion and functionality. It is said to be used by Hollywood celebrities and top athletes. Features: It is a sensory fashion accessory, and it is expected to improve "flexibility," "balance," "endurance," and "concentration" based on medical evidence, but the sensory results vary from person to person. I used it as a wristband for about 3 months only during exercise. The black one is L size and I used it as an ankle band for about a year. I wore it daily, so the camouflage print has peeled off, so please consider it as a bonus. A leaflet is also included. Right arm and left leg... It seems that there is a synergistic effect when worn diagonally. Please purchase with understanding as it is a home storage item. Please check the condition in the photos. Please comment if you have any questions. Shipping included
