This OHSO Pocket Toothbrush actually looks far cooler than it really is, but who cares when you can geek out at your next trans-national sleepover Star Trek convention. The paste is stored in the handle (complete with adapters for major brands) and it fits nicely into the space in your breast pocket between the pen protector and mini duct tape dispenser. $19.99.
OHSO was engineered to be the ultimate travel toothbrush. Besides looking good the OHSO is useful and durable. Toothpaste is stored in the handle for safekeeping and the window shows you how much paste is in the chamber. Turn the knob clockwise and paste is dispensed though the rubber nozzle on the bristle head. Tilt down and paste is delivered directly to the bristles.
