• FOUNTAIN PEN FEEL - 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.
• UNI SUPER INK TECHNOLOGY - An advanced ink formula that bonds to paper fibers, fade resistant, water resistant, and acid free, resistant to chemicals.
• VARIABLE LINE WIDTH - Light pressure will give a finer line as ink is transferred by the ball itself, firmer pressure allows the ink to flow freely around the ball for a thicker line.
• uni-FLOW SYSTEM - Controls and promotes ink flow to the tip, ensuring continuous writing and instant restart of the stroke after use. Perfect for professional documentation.
• COMFORTABLE - 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.

The revolutionary nib of the Air is pressure sensitive, meaning that it gives a writing experience and adjustable line width similar to that of a fountain pen.
