Hand Warmers

Keep your hands warm for a couple hours on the coldest days, even longer than that if its just cold, for a buck. Don't get me started on how warm hands equals a better round.
Just don't get them wet. Wet is bad for hand warmers, exposed to the air is also bad for hand warmers, keep them sung in a pocket. The package says shake 'em for 10 seconds and they'll warm up in 5 minutes. Each package includes one for each hand.
