Specifically designed for using moxa sticks. The top cover itself is held gently in place by several small magnets, and its entire underside has a thin metallic veneer to help radiate heat toward the bottom opening of the box. Ventilation windows on opposite sides help ensure proper burning of the moxa, and a fine metal screen at the bottom ensures that no ash drops onto a patient’s skin. A small nylon cord that attaches to hooks on opposite sides of the box.
