Snapwarmers Self-Heating Gel Packs

TO ACTIVATE HEAT: Using both thumbs and fingers, bend the metallic disc until you feel a 'SNAP'. The liquid will immediately begin to crystallize and release heat. Stays hot for about 20 minutes under normal conditions. DO NOT MICROWAVE. TO REUSE: Take the used pack and stir continuously in a pot of boiling hot water for about 5 to 10 minutes-until the pack contents turn back into a clear liquid. Remove carefully from the hot water and let it cool down before reusing. [Be careful! While boiling, make sure to stir continuously so that the pack casing does not melt. Do not leave a boiling pot unattended.] With proper care, each pack can be reused about 40 times.
