Highlander Reusable Hand Warmers are perfect for cold winter days when just a little bit of warmth can make a big bit of difference. Each hand warmer is a circular pouch that can fit in the palm of your hand and they can be carried easily in a pocket, bag or glove compartment, ready for use when you need them most.

To use, simply flex the metal disk inside the pouch to initiate the chemical reaction that generates the heat. After activating the Highlander Reusable Hand Warmer will maintain a temperature of about 50C for up to an hour. After use the hand warmer can be recharged by boiling it in water until the solid gel crystals turn into a clear liquid again
