These are basically beanbags, filled with rice. I stick them in the microwave for about 30 seconds before I leave, and put them in my mittens, on top of my fingers.
Keeps fingers toasty
Reusable (might have to replace rice periodically, don't know yet)
Only lasts about 15 minutes
Very damp heat
Only useable with mittens
A few years ago someone told us about making footwarmers by microwaving socks filled with rice, so we just adapted the idea. I thought I should share this in case anyone else wants to try it, or has any comments on having done something similar. I like that it doesn't use chemicals and that it is reusable. Maybe different material would produce a dryer heat. These are just terricloth from an old bathrobe I had just torn up into rags.
