The frankly amazing Frixion ballpoint appears here in CDT's trademark black-green colours. In case you didn't know, rubbing the ball tip at the end of the pen against your scribblings causes them to disappear (friction essentially makes the ink invisible).
The Frixion Ball 3 features the three main colours you need to get through life (black, blue and red of course) and writes nicely with its 0.5mm tip. Highly recommended. Refills available in store. Made in Japan by Pilot.
