The OHSO Travel Toothbrush. Replaceable bristle heads, toothpaste stored in the handle, cap doubles as a rinsing cup. Simple genius, and such a pretty design doncha think? $19.95 buys you chrome. Lots of chrome.
Fill your OHSO: a. Remove the replaceable brush head by unscrewing [counter clockwise] b. Screw tight your favorite tube of toothpaste [clockwise] after having squeezed out any excess air in the tube. c. Turn the end cap [counter clockwise]. This will create a vacuum and pull toothpaste into the handle. Turn until the OHSO Travel Brush is fully loaded.
What would be way cooler is if they added a tiny UV led light into the cap so that it would kill bacteria when the cap is put back onto the toothbrush. Could be run by those flat round batteries.
Actually a brilliant idea, and so simple to implement. Nice one. :-)
