This brush might look way too big at first glance, but once people try it, they never go back. The Scuba features a black rubber non-slip handle for easy gripping and an ergonometric design for correct brush angle positioning relative to the tooth, and 6,500 soft, ultra-thin bristles for two to three times the gum and tooth cleaning power of your average brush.
While on the Caribbean island of Tortola, architects James O'Halloran and Kevin Foley came up with an idea for a better toothbrush. In 1982 the original design for the Radius toothbrush was born, featuring an ergonomic handle and 5,500 bristles (the average brush has 1,500). Today, the toothbrush's ergonomic design is featured in the Permanent Collection of the Smithsonian Institute's National Design Museum.
