Our Microwavable Hand Warmers are available in a variety of styles, shapes, and sizes. The mittens come in one size and fit small to large hands. The Palm Packs fit into your mittens or pockets. All of our products, from the traditional Neck Warmers and Back Warmers to all of our Comforting Creatures, can be used to warm hands when they are cold. A Maine Warmer is a comforting gift for someone with arthritis or Raynaud’s syndrome.
