This pack of two hand warmers will offer instant heat on cold winter days and when travelling through cold climates. To use, just pop the metal disk within the gel pad and massage to activate the crystals. Each reactivation lasts for up to 90 minutes and will emit a temperature of up to 54˚C.
These hand warmers have the benefit of being reusable. To re-set the pads, add them to a pan of simmering water until the crystals have dissolved. Allow to cool completely before handling.
