I purchased a box of these hand warmers for my son who is employed as a marine biologist and works mainly on the water in small boats. These, in his words, " were a Godsend during the winter months. He was excited to have received them and has asked for more for next winter. They are individually sealed so they remain effective for long periods of time.
Good for skiing, hunting, snowmobiling. Bought for son for Christmas. Was shipped on time and arrived on time. Good for any cold out door warmth. Could be a life saver if stranded in cold weather.
