This is a small circular magnetic therapy device that can be applied to stiff areas to gently loosen them. It relieves tension and stiffness caused by accumulated tension and fatigue. It's skin-colored and small, making it less noticeable and odorless. You can also take a bath with the sticker on. Since it is a permanent magnet, the effect will last as long as it is attached. We use a bandage that is gentle on the skin and has excellent elasticity and moisture permeability. Recommended for those who often go to college.
