Hey Mari I love those hand/body warmers. Those type of hand,and body warmers are very effective. I used them also when I worked at a Supermarket when it was cold inside,and outside. I was the only one who would by them for some reason. They are well worth the cost. It seems like people who have cold hands all the time don't buy them either. I have about 3 Value Packs of 10 pairs of them on hand. When it's a cold morning on Sundays,I usually give my sister one when she comes to church. I bought mine at Walmart.

There are electric rechargeable hand warmers for sail also. BF
