A Hot Pack yields almost an hour of steady, finger-reviving warmth once activated. Or if you're not too keen on showing the cold getting to you, just leave it in a pocket close to your body for a blast of secret, relatively-high temperature pleasure.
The concept is very simple. Inside the tough plastic shell of a Hot Pack is a thick, clear liquid and a small metal disc. 'Click' the disc and you start a chemical reaction which heats the liquid to a toasty 130F in about five seconds. That's very fast.
Once warm, the Hot Pack remains at a constant temperature for roughly 25 minutes before losing its power of heat. After use, the liquid will have solidified, and all that's required to regenerate a Hot Pack is to heat it in a pan of boiling water until the solid turns back into a liquid. Boil-in-the-bag hotness magic.
There are plenty of times one of these will come in, ahem, handy. On the touchline, on the journey to work, those romantic winter walks accompanied by classic hits during movie montages and many more. Quite simply, warm hands are better than cold ones. Ask any man who's had to drop 'em and cough...

My hotpacks worked the first time and they didn't work the second time :(. Karen, Cwmbran - 10th April 2011

I bought these hand warmers as a Christmas present and we were very disappointed, they worked fine the first time and when we boiled them to reuse them one stayed hard and hasn't worked since and the other stays as a gel and also doesn't work complete waste of my £5. 99, I wouldn't have bought them if I knew you couldn't re-use them!

Fantastic product, was very skeptical about them working effectively but they worked a treat. Snapped the metal and was in amazement with the chemical reaction as the heat was instantaneous! Peter, Bolton - 13th December 2010
Bought sets of these and now its the cold weather they only last about 10-15 minutes before going cold not ideal in the cold weather very disappointing :-( !!! Jonathon Lincoln, Middlesbrough - 8th December 2010

Are they about the right size to put in gloves to keep hands warm? Anna, GB - 4th December 2010
Firebox says: If the gloves aren't too tight, we can't see why not.
