Yes. Maine Warmers can be frozen and used as ice packs as well as heating pads. They are as gentle as they are versatile. Place in the freezer for a few hours then place on the affected area. A plastic bag may protect it from becoming soiled while in the freezer. Enjoy a gentle cold that isn’t harsh like ice cubes – without the mess of melting ice. If you keep a Maine Warmer in the freezer all of the time you’ll have instant relief for burns, bumps, & bruises.
