Although single-use heaters have their fans, the Savotta hand warmer model is more ecological as you can reactivate them time after time. When you activate a heater bag, it will give warmth (approx. 45°C) for about one hour. As the chemical reaction takes place, the bag will turn from gel-like to rather stiff and the contents will turn opaque. Great for keeping your hands warm, or warming camera batteries, giving a gas cartridge a bit of a boost etc.

Use: press the activator you can see inside the gel bag
How to reactivate:
1: submerse the bags in boiling water and wait until the contents turn clear (6 to 8 minutes)
2: take bags out with a spoon or something similar
3: let cool
4: ready to go!

Sometimes a bag will activate inside its original package. You can recognize an activated bag by its opaque looks and stiff structure. To solve the situation, just follow the regular reactivation procedure.
