We all heard of "tennis arms", but if you chill easily and work on a computer a lot, you will know what at "mouse hand" is. I used to get so cold in winter (or summer with the a/c blowing) that I occasionally had to go and run hot water on my hands (yes, bad, I know).
But no more. I wasn't sure about wrist warmers, but LOVE THEM. Only have one pair so far, but the reason I am on here is to order at least one more. This is an easy recommend.
