Uni-Ball uni-ball AIR Micro - 0.5mm Fine Rollerball - White Barrel - Black Ink - Pack of 3 - UBA-188E-M

Pack of 3 Liquid Ink Rollerball Pens from Uni-Ball. About this item The revolutionary nib of the Air, unlike conventional rollerballs, is pressure sensitive, meaning that it gives a writing experience and differentiating line width similar to that of a fountain pen. The metal ball of the nib is encased in an acetal plastic, rather than the standard metal surround, which allows for a smoother flow of ink around the ball, 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 Micro has a 0.5mm tip that writes between 0.28mm and 0.45mm. This set contains three pens with a white barrel and black ink. › See more product details
