Hand and Body Warmer - Heart 1 pc ISO

The perfect hand warmer and not just for hands, reusable multiple times! Simply press the metal disc inside and the substance will immediately start to crystallize, causing the heart to emit heat (about 50-60 degrees). The heater is safe – it does not contain harmful chemicals – it is a safe salt crystallization process!

The heart will slowly cool for about an hour (the time depends on the ambient temperature; kneading the heater will prolong the process).

When the heart turns white and cools down, simply place it in hot water and boil for a few minutes (about 5-10 minutes; there's no need to fear boiling, the heater won't be damaged - it's designed for this) and then let the heart cool down completely – and you can enjoy the heater again – now just press the plate again (preferably in a different spot – where you can see slight notches with a bulge).

Instructions:

1. Bend the metal plate at the center of the heart
2. The interior crystallizes within a few seconds and reaches about 50-60 degrees
3. After cooling, boil the heart in hot water for about 5-10 minutes to turn it back into a gel and let it cool down, then you can use the heater again (again bending the sheet metal)
