The nano-mineral coating technology, Nano-Shion Dream Technology, applied to the bristles allows you to clean your teeth simply by soaking the bristles in water and brushing. This innovative toothbrush allows you to brush your teeth with just a glass of water, contributing to the protection of the global environment. It has sold over 4.5 million units in Asia and other countries. With the power of the nano-mineral processing applied to the bristles, you should feel a unique smoothness just by "brushing" with water. However, don't be satisfied with the smoothness. Please carefully feel the surface of your teeth with your tongue after brushing. There will surely be areas where the "smoothness" is weaker. Please brush only those areas again intensively.
