If you live in the north country like I do, a good hand warmer is a must. Finding one that actually works as claimed is truly a blessing. I've toyed lit sticks in my pocket, boiled solution bags. All have failed to live up to my expectations until now. If you need a burst of heat just remove it from the carry bag and it really gets hot! Butterfly Pattern Hand Warmer is perfect for people who live in cold weather or outdoor activities such as fishing, hunting, skiing. The Pocket Hand Warmer is made from rugged material with no seams, to prevent leaks. The platinum-catalyzed fiber burner offers quick and sure lighting. It is just for you, so what are you still waiting for?
