This kind of toothbrush can store and provide water, it is designed for Africa and other water-shortage areas. This product combines toothbrush with glass together and makes full use of the internal space of toothbrush and store water. You just need to push lightly and the water will flow out from the brush head. The more strength you use, the more water you will get. Meanwhile, the method that pushes the toothbrush to get water can also reduce the operational program of brushing teeth and save time of users. Storing water meets the demand of water in water-shortage areas. It is very convenient for us to go out without glass.
