Our Solid-Fuel Pocket Hand Warmer will keep your hands comfortable in freezing cold situations. Just ignite the solid fuel stick with a match and place it in the velvet-covered, fiberglass-insulated case. One stick can generate heat for four to five hours of heat. It can be easily stored in a pocket for instant heat relief. Weather you are playing sports, shoveling snow or camping, if the temperature starts dropping, you do not want to lose control of your hands because it is too cold. Our Solid-Fuel Pocket Hand Warmer is sure to warm up your days and nights.
