Freehand / toothcleaner


As we get busier and busier, we found that toothbrush has several shortcomings, first of all is that when we brushing teeth, we could do nothing else at all.
Our Freehand is design to free your hand. Freehand looks like a teeth protector for athletes. It cleans teeth by ultrasonic, all you have to do is putting it into your mouth and bite it gently, the ultrasonic wave will clean your teeth automatically. So your hand is free now and you can cook or do anything you want when you cleaning your teeth. One more thing, the toothpaste will never corrode your teeth any more.
It also contains a base which charges for freehand, and also cleanse it.
