The Uni-ball Air pen gives you the freedom of a fountain pen with the security of a roller - no leaks here. Unlike other rollerballs, the Air's metal ball is held in a plastic surround, allowing the ball to move and meaningless friction when the pen is held at an angle.

Light pressure will give a finer line as ink is transferred by the ball itself, whilst firmer pressure allows the ink to flow freely around the ball for a thicker line. The Air contains Uni-ball's famous Super Ink, which is fade-resistant and water-resistant and tamper-proof. Average line width between 0.35mm and 0.55mm varies with the pressure applied, giving you total writing freedom.
