With the same award-winning design that landed RADIUS in the Smithsonian, the Soft Left Hand SCUBA Radius Toothbrush puts a fun and functional twist on your daily brushing. The SCUBA is made from flexible recycled rubber, providing more give and grip for the most effective clean yet. The wide oval brush head, featuring durable vegetable-based nylon bristles, has a flexible neck to get into nooks and crannies with ease. Plus, the user-friendly left handed handle complies with the dentist-recommended 45-degree brush-to-tooth angle, with a smart "thumb-and-palm" design for maximum control.
