The Kanjo Heat Therapy Pillow offers a simple yet effective at-home solution for neck, leg and stomach pain. Taken from ancient Eastern methodologies used in acupuncture, the Heat Therapy Pillow targets acupressure points to reduce pain with the added benefit of hot or cold compress therapy. Our plastic stimulators are custom designed to ensure maximum coverage, resulting in the activation of several acupressure points at once. The internal water bottle can be filled with hot or cold water for soothing hot or cold compress therapy. This product contains natural rubber latex which may cause allergic reactions.
