Air Medium – UBA-188-L
UBA-188-L | Nib size: 0.7mm
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 meaning less 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 also contains uni-ball’s famous Super Ink which is fade and water resistant and tamper proof.
Average line width between 0.355mm and 0.55mm varying with the pressure applied, giving you total writing freedom.
Available in black, blue and red.
