Micro Beads are a natural and drug free method to help relieve muscular aches and pains, arthritis, fibromyalgia, cramping, headaches and more. Packs can be warmed in a microwave to desired temperature and will remain warm for 20-30 minutes. Micro Beads adsorb moisture from the air and release it when heated, delivering soothing moist heat. The plush fabric of Micro Beads is soft to the touch and gentle on skin. Made with high quality fabric and the finest stitching, each pack is embroidered with the Core Products logo. Baffled channels help keep beads evenly distributed and packs easy to handle.
