Preserve consulted closely with dental professionals to create a toothbrush that gets your teeth cleaner but minimizes your impact on the environment. The design includes a curved handle for those hard-to-reach places and a three-level bristle arrangement to massage your gums. And while the bristles are brand new, the handle is made from recycled yogurt cups. The reusable, clear Travel Case features ventilation holes and a cap to keep your toothbrush clean and dry wherever you take it or store it.
