They stay hot 🔥 a very long time. That's a big plus for me because I work in the weather 🌡️

Good hand warmers buy them every year

Great for warming hands.

These saved me when no electricity. Placed them in my gloves and in my shoes. Previous year I got frost bite. My toes turned black and when they thawed out, it felt like my feet were being held over an open fire.
