Fun With Curaprox. Smile brushing your teeth because you're thinking of a laughter from the weekend. The Czech designer Alžběta Vaculíková brings fun and joy to the bathroom with a stylish CS 5460 toothbrush in unusual but fascinating burgundy red. The Special Edition toothbrushes are the result of collaboration with established and emerging artists from all over the world. They were all surprised when they were commissioned to design a toothbrush. Meanwhile, the artists use the CS 5460 themselves.
