The surgical elastic design has made the wrist guard a great compression support. The magnetic wrist support may be beneficial for the relief of arthritic pain, muscular aches and pains. We have enhanced the support of the guards with twelve extremely powerful 3000 gauss rare earth magnets. The new cutting edge in magnetic therapy. For hand and finger pain place the magnets in the underside of the wrist. For wrist problems place the magnets directly on the pain point. Care instructions: Gently wash under running water with liquid soap. Customer Letter: For the past ten years I have suffered from tendinitis in my wrists. I had tried everything for the pain relief with little success. When I first tried the magnetic wrist support it took less than a day for the pain to go away. Now if I feel a twinge of pain coming on, I put the magnetic wrist support on straight away and the pain is gone within a few hours. Kind Regards Miss S Bailey.
