The ULTIMATE Travel Toothbrush! Radius has changed the game and made it super easy (and fun) to brush on the go! With its "Jack-Knife" design, easily tuck away the brush-head into the handle and you're all set! No other accessories required! If that wasn't cool enough, this awesome brush is made with 100% wood-based bio-plastic and the bristles are derived from vegetables! Can you say environmentally friendly??
