333Brush / Zahnbürste


A habit of brushing teeth at an early stage of life determines lifelong health of teeth.
This 3 3 3 toothbrush helps children to develop an ideal habit of brushing teeth for three
minutes by signaling time passed since they began tooth-brushing.
When a child begins to brush teeth, a button inside the toothbrush starts the
operation of a timer. Sound and lighting continue only for three minutes, du-
ring which a child can brush teeth with fun.
