Introduced in the market last year in September and sold only in big department store in Tokyo, this new style of tooth brushing seems to appeal certain segments, since it has so far sold about 800,000 products. The tooth brush is made of special brush and coated with certain substances that reacts with water and therefore can clean the teeth without having to put tooth paste.At 1050Yen it is more expensive than ordinary toothbrush. Most of users are apparently those people who travel frequently, children who do not like toothpaste and the elderly. I wonder how long this product will remain popular and whether the trend will spread to other cities in Japan.
