These special Air Micro coloured barrel design offer the same fantastic features you know and love from the standard barrel, but come in 4 colour variations allowing you to choose the design that you love. The ink itself is black in all colour options. The uni-ball Air Micro pen is similar to a regular fountain pen, but without the leaks. Unlike other rollerballs, the Air Micro features a ball which can move freely within a plastic surround, resulting in far less friction when the pen is held at an angle.
The Air contains uni-ball's fade resistant, water resistant and tamper proof Super Ink.
Writing with less pressure will deliver a finer line as ink is transferred by the ball itself, whilst pressing a little harder on the surface gives a thicker line as the ink is able to flow freely around the ball.
The Air Micro will give you a slightly finer line width than the Medium - between 0.25mm - 0.45mm.
Available in black ink.
