The 05mm ball delivers a line width of between 028mm and 045mm dependent on pressure. The revolutionary nib of the air, unlike conventional rollerballs, is pressure sensitive, meaning that it gives a writing experience and differentiating line width similar to that of a fountain pen.

The metal ball of the nib is encased in an acetal plastic, rather than the standard metal surround, which allows for a smoother flow of ink around the ball, and an increased flow as further pressure is applied.

Sleek, elegant look and feel that is comfortable and easy to grip, capped top stays put and ensures that this pen will never leak in your pocket. Freedom of a fountain pen with the security of a roller-ball with no leaks, the Air’s unique metal ball can move without friction when the pen is held at an angle.

Features uni's high quality "super ink", but also "Tamper-Resistant", which is not only water and light resistant, meaning that the ink cannot be washed off using chemicals and solutions used by people to fraudulently modify documents.
