Product Description

Go from cold hands to blissful warmth in seconds. Hand warmers keep you comfortable all winter long!

How To Work?

The hand warmers are decidedly low tech and rely on the miracle of chemical reaction to produce their hand-saving effects.

When you break the seal on a hand warmer, you set in motion a process called oxidation. Air sifts into the packet through tiny holes in the pouch and reacts with the iron inside. Iron oxide (more commonly known as rust) is then created. Salt is used to generate heat and vermiculite in the warmer then absorbs that heat and prevents it from escaping. Carbon (also in that busy little bag) is then employed to disperse the heat throughout the sack so that when you hold it, the entire bag feels warm, not just one particular area. There are no fancy-pants energy banks or LED flashlights on offer here. But these little sacks of heat may be the best hand warmers for winter. You can even put them in your winter boots to heat them before you wear them.

Note:

Store in a cool dry place.

For maximum efficiency, place warmer in pocket or gloves.
