These do exactly as advertised. They are warm. A box of 40 is good as you will need to use more than one. After about 10-15 minutes you will feel the warmth. Shake occassionally to keep the activation going. I tested one and it lasted about 12 hrs. Be caredfull when opening the box of warmers. Don't use anything sharp. The warmers are not protected.

They are warm and easy to use, also last about 18 hours. The problem is that the label said one box contains 40 pairs, actually, it is 40 single package. Kind of misleading or confusing labels.

These are so comforting when you are heading out in a cold and rainy/snowy day. You have a secret pal in your pocket! Do not delay in buying these if you need a little pick-me-up during this foul weather.
