The 05mm ball delivers a line width of between 028mm and 045mm dependent on pressure. The metal ball of the nib is encased in an acetal plastic, which allows for a smoother flow of ink around the ball, rather than the standard metal surround, and an increased flow as further pressure is applied.

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

The air pen contains uni-ball’s super ink which is not only water and light resistant "Tamper-Resistant", meaning that the ink cannot be washed off using chemicals and solutions used by people to fraudulently modify documents.
Unlike other rollerballs, the air features a ball which can move freely within a plastic surround, resulting in far less friction when the pen is held at the right angle.

Each pen contains black ink and has a 05mm tip that writes a slightly finer line than the medium. When writing with less pressure you will receive a finer line as the ink is transferred by the ball itself, whereas pressing a little harder gives a thicker line as the ink is able to flow freely around the ball. Unlike other rollerballs, the air features a ball which can move freely within a plastic surround, resulting in far less friction when the pen is held at the right angle.
