An amazing piece of heat-tech, this Neck And Shoulder Pad is head and shoulders above anything else out there when it comes to soothing aches and pains. Simply click the metal disk and the liquid in the warming pouch crystallizes in a fun-to-watch chemical reaction that generates heat for up to two hours. When you’re done, just boil the warming pouch until the crystals have melted and you’re ready for a click of the metal disk and a new round of mending warmth.
Heat pad can be used anywhere on the body. Provides up to 2 hours of heat before gradually cooling down to room temperature. Contains water and food-grade sodium acetate (a form of salt). There is no limit to the number of times a pack can be used. Suitable for children, adults, and even pets. To use as a cold pack, place in refrigerator for 20-30 minutes.
