Roll out tight, muscles while helping to release toxins and improve circulation. Made from natural cork, this firm roller is a powerful self-healing tool that can improve joint movement, relieve pain and calm your nervous system. Lean into a wall, or the floor to create just the right pressure to roll out your back or big muscle groups like hips and legs. Roll along arms to relieve wrist and hand pain. Small and lightweight so you can take it with you to yoga or the gym
