About the product

The toothbrush is made from Miswaak root kneaded into the bristle of the Smart Miswak. The Black Silica can be founded in a limited area called "The Milky Way" of Hokkaido in Japan. The Black Silica is known as a natural ore generating negative ions and far-infrared effects. This means it can improve blood circulation in the skin and internal organs, and supports cardiovascular health.  Hence, the Black Silica supports the function of brushing the teeth with only water.
