It is heated by placing it in hot water. The gel liquid solidifies after losing its heat. How to Use: Crack the metal circle inside the package with your hand. The metal chip acts as a catalyst, after which the heating gel will solidify. The temperature will gradually decrease after 30-40 minutes. Once completely cooled, heat it in boiling water until all the crystals have gelled (5-10 minutes). As long as there are no cuts or tears, and the chip is not broken, you can use the heater repeatedly. Cautions When Using: After use, you can re-boil the product to liquefy it and use it again. However, do not crack the metal flake immediately after boiling. The product may have been activated during shipping and may be solid upon arrival. This does not mean the product is defective. You can boil the product to liquefy it again and use it whenever you like. How Does It Work? You crack the metal inside the Magic Heating Gel. During this time, micron-level energy activates the Gel, and our metal chip acts as a catalyst. As a result of the reaction, the liquid sodium acetate salt turns into a solid and releases heat during this phase change. This temperature reaches 55 degrees Celsius and continues for 30-45 minutes. Then, we boil the Magic Heater, which has cooled from its solid state, to transform it back into a gel state and become a potential heat source. Where can I use the Magic Heater? It can be placed on the abdomen and feet for abdominal pain. You can safely warm your bed or pillow by placing it in your bed 5-10 minutes before going to bed. It can be used to warm the inside of your jacket while skiing, hiking, running, or running; to warm your overalls for mountaineering, camping, and hunting; for dressings in areas requiring pain and hot compresses. To provide instant warmth to areas that need to be kept warm, where it is needed. Contact us for wholesale square gel heaters. Product dimensions: 7 cm x 7 cm Package Contents: 1 Square Gel
