The Ocoopa rechargeable hand warmers have an excellent price. I love this brand and these warmers have 16 hour warming life. They heat up in about 4 seconds… I’m not even kidding. I love the size and that they store as one unit because they are magnetized!This a fantastic gift for anyone that works or enjoys sports outside. Sophie already has a pair when the temps start to get frosty in Boston. Clip digital q-pon and enter LHERTNUL to drop them to $17.99. Xo, Donna
