Snap It Hot/Cold Reusable Gel Heating Pad for Pain Relief - 5 Pack

HOW IS THE HEAT PRODUCED? The heat is produced by bending or “clicking” the coin located in the liquid pad. This action causes a reaction that leads to the crystallization of the liquid, resulting in the release of heat. It is important to note that after the liquid has crystallized, massaging the pad will make it soft and pliable, allowing it to stay hot for a specified amount of time depending on its size. The crystallization always occurs at a temperature of 54°C (130°F), and the pad will not activate if it is above this temperature.

Once activated, the heating pad has a predetermined amount of energy available to it. It uses this energy to increase its temperature to 54°C and utilizes the remaining energy to maintain that temperature. This ability to produce heat for a period of time is due to the fact that not all the liquid crystallizes immediately. The molecules that were not needed to heat the pad to its maximum temperature remain liquid and crystallize as required to maintain the maximum temperature. This means that a warm pad will retain its maximum temperature for a longer duration compared to a cold one.

LONG LASTING INSTANT HEAT PACK - The click hand warmer employs unique technology to release heat without electricity. It uses a safe sodium acetate solution, which undergoes a phase change from liquid to solid when activated. Within seconds, it reaches a temperature of around 130 degrees and can provide heat for approximately one hour, depending on its size and insulation.

VERSATILITY - These soft and flexible heat pads can easily adapt to complex areas of the body. They not only serve as hand warmers but also offer relief for arthritis pain, muscle pain, tendinitis, shoulder and neck pain, back pain, knee pain, and menstrual pain.

EASY TO USE - The heat pad can be refrigerated for cold therapy, but it should not be frozen. To activate the heat, simply bend the inner disc, and it will reach a temperature of 130 degrees in just three seconds. After use, it can be cooled down by boiling in water for five minutes. Place a rag underneath before boiling, and once the hot compress bag returns to its liquid state, remove it and let it cool for repeated use.

SAFE AND REUSABLE - This reusable hand warmer is made of environmentally friendly, high-quality, medical-grade materials that are durable. It can be reset by boiling in water to liquefy the crystals. For optimal results, please cool down and store the pad in its liquid form.

EMERGENCY NECESSITIES - The reusable hand warmer is designed for comfort, pain relief, and instant heat. It is a portable and long-lasting heat pack that can be used multiple times, making it ideal for family first aid, camping, outdoor sports, emergency situations, hiking, and sports events.
