Reusable hand warmer for very cold days. Suitable for frostbitten fingers or sore muscles. Pack of two. Carry the hand warmer in your pocket or glove when fishing, hiking or doing other outdoor activities. Suitable for frostbitten fingers or sore muscles. Instructions for use: Rub the metal plate back and forth until crystals form. The mixture will heat up. To dissolve the crystals, wrap the bag in a towel and immerse it in boiling water for approx. 7-10 minutes (or until the crystals are completely dissolved). Let it cool before use. When used correctly, the hand warmer can be used more than 100 times. The hand warmer releases heat during crystallization and absorbs it during melting. The heating effect decreases with each use.
