This premium hot pak from Warmies is a wonderful thing when you want some soothing heat applied to achy muscles or joints. This one is covered in a pretty pink knit with white snowflakes and poms at the end. Inside, it uses clay that is chosen for its ability to stay warm for a long time. So you can simply microwave this for 90 seconds and enjoy soothing heat. Or, place in the freezer for 3 hours, and you'll get lasting cool therapy. This long hot pack bends, molds, and folds, so you can use it for elbows, stomach, neck, back, knees, hands, or feet. Made by Warmies, a division of Intelex USA. This measures 10 by 5 by 3 inches.
