Details:
When Thera-Bead packs are heated in a microwave oven they release their retained moisture, providing pain relieving therapeutic moist heat. After treatment the amazing Thera-Beads rejuvenate themselves by recovering moisture from ambient air. Because of this phenomenon, Thera-Beads, with proper care, can be used indefinitely. Recommended for treatment of chronic pain. All sizes complete with cover. 6 1/2" X 22" (16 X 56 cm) Specially contoured for aching neck and shoulder muscles.
