The Wonder Pax BACK Reusable Warm/Cold Gel Pack Brand New (Yellow)

Warm Compress: WonderPax is an instant, portable and reusable warm gel pad. At the click of a button the pad will reach 130°F(54°C). Place a damp cloth/belt between the WonderPax and your body and feel the heat quickly penetrate muscles and joints. The pad contains sodium acetate, a salt-based solution, tightly sealed in a durable pack. Flex the small metal disc inside the pad creates a molecular reaction, causing the solution to crystallize. During the reaction (liquid to crystal form), energy is released in the form of heat. By boiling it in water the exothermic reaction is reversed so that the pad may be reused again and again. Cool Compress: Store WonderPax in the REFRIDGERATOR indefinitely until ready to use. The product remains soft and flexible at refrigerated temperatures. The cold pack soothes the desired area within 5 minutes, without the harsh shock and pain experienced with ice water treatments. WonderPax warm and cool gel pads are ideal for use on the back, shoulder, hip, thigh, elbow, neck, wrist, or any part of the body where therapy is needed. *Sports therapy in the case of muscle joint strains and inflammation. *Arthritis pain relief. *Deep penetrating heat therapy and circulation stimulation *Therapeutic treatment of tight muscles, spasms, and joint pain. *Enhancing the warm-up period before exercise by loosening tight muscles and joints.
