These Hot Stuff Hand Warmers are great for keeping those winter chills away. Simply crack the disc inside the 3 inch wide hand warmer & you will have instant heat for around 20-30 minutes. When you crack the disc you set off a small non-toxic chemical reaction which heats the liquid to about 130F in about 5 seconds. Re-use time & time again! To reuse simply heat the hot pack in boiling water until the liquid goes clear, leave to cool & crack when ready days or even weeks later. The Hot Stuff Hand Warmers are the best way to keep you & your hands warm, whether you are on a camping trip, climbing a mountain or just outside in the cold weather. So small they fits in your pocket & makes an ideal travel companion.
