These ingenious new bead packs can provide both hot and cold therapy care. We want you to RAK the planet so we thought these earth shaped packs were quite fitting! They are filled with gel peas that mold to your body with ease. Can be used over and over, simply microwave for hot therapy, or freeze for cold (detailed instructions are printed on back of each pack). These products are not intended for use by children or pets. They may present a choking hazard to children less than 3 years of age. Packs should not be used on infants.
