Leucas Brush is a whale-shaped toothbrush designed for children to help them form a habit of brushing their teeth actively and happily. With the feature of turning the kinetic energy of swaying the brush into the beautiful bubbles popped up at the end of it, which is also the mouth of the whale, children will not feel brushing their teeth is a tedious or boring task and parents will not worry how to convince their children to brush their teeth anymore.
