Great for taking along on trips or storing in your car, the Heat Factory Hand Warmers provide instant warmth to your hands, head, and other parts of your body when used with Heat Factory accessories in the chilly outdoors. Each warmer is non-toxic, odorless and provides up to 10 hours of reliable even heat.

Features:

• Soft, lightweight pouch containing a biodegradable mixture of iron powder, charcoal, salt and vermiculite. When exposed to the air, an oxidation process takes place that generates heat.
• Specially engineered to provide quality heat that is long-lasting, comfortable, and even.
• Once activated, Heat Factory warmers can even be saved for later use (preferably within a week) if placed in an airtight container. Unopened, the Heat Factory warmer has a shelf life of three years or more.
• Proudly designed and hand-made in the USA
