The RADIUS Tour Travel Toothbrush is uniquely designed to provide a deep and soft massaging clean unlike any ordinary travel toothbrush on the market today. It is constructed with a clever "jack-knife" handle functionality that hides the toothbrush replacement head inside the handle when not in use, acting as an all-in-one travel case and toothbrush. The handle is made with 100% cellulose propionate, the same wood-based bio-plastic used for the zero petroleum RADIUS Original Toothbrush. The head is 100% replaceable and is interchangeable with all of the well-known RADIUS Source Toothbrush Replacement Heads to allow consumers to easily exchange the heads after travel and general use without throwing away the entire toothbrush. RADIUS s products are made to last which means they are being used longer and not filling up the landfills as quickly while still providing you with the excellence you have come to expect from RADIUS. RADIUS operates in a women-owned, family-run and operated solar-powered facility in Pennsylvania. Each product is designed in-house in Kutztown PA, inspected by hand and designed to last. Made in the USA.
