These adorable knitted Cat design hand warmers will have your hands warm in no time. Each knitted hand warmer contains a reusable click gel heat pack.To heat simply hold the metal chip inside the hand warmer between your thumb and forefinger and bend gently until it clicks. The solution will crystalize and release heat. Massaging the pack will help maximise the heat. The hand warmer will stay warm for about 45 minutes. You can reactivate the gel pack when cold and hard by placing in a pan of boiling water and simmer for approximately 10 – 15 minutes or until the crystals disappear. Allow the water to cool before removing. Once it has cooled it’s ready to use again.These fun hand warmers are great for keeping out the winter chills and keeping your hands toasty and warm. Simply hold one in each hand or slip one into each of your pockets. All our knitted hand warmers are boxed in pairs. Instructions for use can be found on the packaging and gel packs. Knitted hand warmers make the ideal gift for friends, family and loved ones.
