Handeze traps your natural body heat, which stimulates increased blood circulation in the wrist, hand and fingers. This reduces swelling and helps maintain flexibility. The form-fitting design provides additional support for the muscles, tendons and ligaments of the hand and wrist. The four-way stretch material reacts to each movement of the hand, producing an automatic massaging effect. The combination of these three proven pain relievers - heat, support and massage - provides you with a uniquely comfortable and flexible method of reducing hand pain, stress and fatigue.
