Features:

• Long-Lasting: Provide an amazing 20 hours worth of heat, unlike other varieties of hand warmers which only provide 6-8 hours.
• Super-Warm: Capable of producing heat as high as 155 degrees, helping to warm up your body in a matter of moments. The entire time they're open they'll give off a consistent 130 degrees of heat, more than enough to help you stay warm when it's brutally cold.
• 100% Safe: Because they rely only on oxygen to stay warm they're perfectly safe for use in a variety of circumstances. 
• Compact: Small enough to fit in the palm of your hand (or in a coat pocket) for ease of use and the ultimate in portability.
