The MISOKA • ISM toothbrush has nanomineral-coated bristles that polish your teeth as you brush, cleaning them with nothing but a cup of water. Usually, toothbrushing wastes a lot of water, which damages the environment, but this eco-friendly toothbrush solves that problem. MISOKA toothbrushes are popular in Asian countries because of the unique properties of the nanominerals, which cause the tooth’s surface to attract water and become smooth and impurity-free. The textured handle, modeled on flowing water, aids grip and helps the tapered nylon toothbrush hairs move smoothly over your teeth and gums. The ultimate in toothbrush perfection.
