To Activate the Click & Heat Gel Pack:
Hold the metal disc inside the click and heat gel pack between your thumb and forefinger and bend it gently until it clicks. The solution will crystallize and release heat. Massaging the click and heat gel pack will help maximise the heat given from the hand warmer. The hand warmer will stay warm for about 30-35 minutes.
When the click and heat gel pack is cold and hard, place in a large pan of boiling water and simmer for approx 10-15 minutes or until all the crystals disappear. Keep the PVC material away from the sides of the pan during the re-heating process. Allow water to cool down before removing the click and heat gel pack. Once it has cooled it`s ready for you to use again.
