Our Microwavable Hand Warmers are available in a variety of styles, shapes and sizes. The mittens are designed as “one size fits all” for 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 cold hands. A Maine Warmer is a comforting gift for someone with arthritis, poor circulation or Raynaud’s syndrome.
