Uni-Ball AIR - 0.7mm Medium Rollerball - 6 Pack - Blue - UBA-188-L

Features

• 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. The 0.7mm ball delivers a line width of between 0.35mm and 0.55mm (dependent on pressure).
