Amazon's Best-selling Hand Warmers Make the Perfect Last-minute Stocking Stuffer-and They're Under $30

"Just $28, the Ocoopa hand warmers have more than 7,000 five-star ratings and have been purchased almost 150,000 times in the past month alone. That's about three times every minute, around the clock. While searching "hand warmers" on Amazon yields more than 10,000 results, these have apparently beat out every other option for their quality, size, battery life, and more."

"Each warmer is less than an inch thick and weighs just over two ounces, so it's small enough to shove into most jacket pockets or even mittens. They operate with one button, which controls three temperature settings. The lowest setting heats up to 108 degrees, the second setting to 117, and the highest to 126. "They heat up faster than my morning coffee," one reviewer said. "Seriously-seconds!""
