The heating pad in a decorative plush cover with a HEDGEHOG motif is used to warm hands, gloves, shoes or pockets in cold weather. Suitable for skiers, hikers, etc. It fits comfortably in your pocket. The plush cover is removable and can be easily washed at 30 °C. The heater contains a liquid gel and an activation plate. To activate, simply break the plate inside the heater, which will trigger a chemical reaction, when the gel begins to crystallize and heat. It can be used repeatedly. To restore the function, simply boil the inner part of the pad (heater) in boiling water for a few minutes after it has cooled down, until the gel crystals dissolve. You can then use it again. The heat retention time is approximately 15 to 30 minutes, depending on the ambient temperature. It can also be used as a cold compress by cooling in the refrigerator or freezer.
