Description Finely ground charcoal and moxa herbs are compressed into perfectly formed caps. Ondan Moxa is a product that has revolutionised traditional needle moxa use. It is smokeless, odourless and burns down to a solid ash which is easily removed from the needle head. Each piece burns for approx. 7 minutes, making it easy to calculate your use time. Ondan Moxa allows the full benefit of moxa, without the danger of falling embers or the irritation of smoke. Trapezoid shape Box of 450. Made in Japan.
