The oral care brand of Japan's Sunstar Group, in cooperation with G· U· M, Ora2, Butler and other brands together form the oral cleaning business, competing with brands such as Lion King and Robesch in the Japanese oral products market. Do Clear specializes in home oral care, and children's products are sold well in Japan.
 
With only one children's toothbrush series, Do Clear is also known as the Qiaohu toothbrush, which was launched in collaboration with the Benesse Group, Japan's largest educational brand, and was designed based on the feedback of parents who participated in its exchange seminars, and using the image of the institution, which is loved by children.
 
Qiaohu toothbrush has a total of four products, respectively for parents over 6 months old, 2-4 years old, 4-6 years old and 6-12 years old, all of which use soft bristles. U· Compared with M. Miffy children's toothbrushes, the handle is thicker and rounder, and there is soft rubber non-slip, which is more suitable for children to grasp. However, there are only three types of toothbrushes used by children in Chinese e-commerce channels, which are not suitable for parents to use to help their children brush their teeth, and the brush handle and packaging are not printed with Qiaohu, and the price of a single toothbrush is higher, at 18 yuan. Japanese-made Qiaohu toothbrushes can only be purchased through overseas shopping, and the price is not much different from the e-commerce sales price.
