Product Description

Perfect to slip into your pocket and keep your hands warm on those cold winter days or to keep in your emergency kit just in case. Flexing a catalyst disc in the hand warmer causes the liquid in the pouch to crystalize, generating heat. To recharge, simply place in boiling water to melt the crystals back into a stable liquid. Directions are printed right on the warmer.
