Hand warmers are a must-have item during the cold season, whether you're commuting to work or school, or going to outdoor leisure activities or events. We offer a wide variety of hand warmers to meet customer needs, including those that warm up quickly even outdoors, those that don't get lukewarm easily, and colored ones.

Why does a hand warmer get warm?

The contents of a disposable hand warmer contain iron, water which speeds up the rate at which the iron rusts, salts, vermiculite which acts as a water retaining agent, and activated charcoal which absorbs oxygen from the air.
If iron is left alone it will rust.
This is because iron reacts with oxygen in the air to produce iron oxide.
Disposable hand warmers utilize the heat that is produced during this chemical reaction.
