Moist heat packs are different from other like grains, seeds, or gels in that they produce moist heat by absorbing water molecules from the air. When activated in the microwave, these molecules are released in the form of soothing moist heat, lasting up to 30 minutes.
They produce "clean moist heat" and remain odor free. Packs will not support mold, bacteria, or fungi growth.
