HotHands Hand Warmers - Long Lasting Safe Natural Odorless Air Activated Warmers - Up to 10 Hours of Heat - 40 Pair

These were good and worked as described. I also tried electric hand warmers and personally think electric are the way to go because you can turn those on/off. Also if you are traveling then the electric ones are easier to travel with. These were great though, so i'd say just a matter of preference. I recommend!

I've used these for years, mostly in the winter, on the tractor, clearing my and neighbors driveways of snow, and a bit of hunting. As I age, my hands have become more sensitive to the cold. Simply slip these in my gloves (the type with warmer slots on the top inside) just prior to jumping on the tractor and the 2-3 hrs moving snow is no problem. I highly recommend these.

El paquete se debe de abrir con algo punzante, una llave o que tenga filoso.Funciona perfectamente. Gracias

This item speaks for itself. The price is great If you absolutely work in environment where you need these they're awesome.

Hot Hands hand warmers are fantastic! They are so easy to use and I love the convenience of the individual wrapping. Just grab, go, and stay warm!

I love these for my early morning dog walks. They keep my hands toasty and warm. The only reason I deducted a star is that I don’t believe they are environmentally conscious. I try to use them just when it is really cold, but wow, are my hands happy with them in my gloves.

Good hand warmers in a big enough quantity to last at least a couple winters

Best hand warmers in the market. Use them in my shoes mostly and they are thin enough to not cause discomfort with socks on. They last most of the day, depending on the temperature outside. Usually 6 to 7 hours.
