Tombow Airpress Ballpoint Pens

The Tombow AirPress ballpoint pen uses an ingenious mechanism to pressurise the ink with every click, enabling this pen to write under otherwise very difficult circumstances. This pen writes upside down, on wet paper, dusty surfaces, even in space! The special ink also allows this pen to write in very cold conditions. Tombow is proud to have some of these pens overwintering at SANAE IV in Antarctica! The spring loaded clip opens wide to grip onto thick materials without bending. Show More Show Less
