Insta Heat Reusable Hand Warmers - 10 Pack

This listing is for instant heating gel hand warmers, oval shaped and larger than most standard hand warmers at 10 x 8.8 cm. Perfect for cold days out and cold days in the office or at home. Use these when at a football or other sports match, when out skiing or in the cold weather and also just when at home for those times when you can't seem to warm up. The item instantly heats up, simply click the metal disc inside the hand warmer and wait for the liquid to crystallise and heat up (on the first go it may take a few clicks). The items will give off heat for up to 10 minutes, depending on the outside temperature, manipulating them with your hands will maintain the heat for the longest time. The items are reusable, to reuse please follow these instructions, simply putting them in a bowl of hot water for 10 minutes will not work. The items need to be placed in a pan of constantly boiling water for around 10 - 15 minutes, it differs slightly for each hand warmer. The temperature of the water is very important and is the thing which makes them reset, if it is not constantly boiling then they will fail to reset.
