Uni-Ball Air Roller Ballpoint Pen Blue

Uni-Ball UBA-188-L Air Broad Roller Ball Pen writes like a fountain pen. Revolutionary plastic acetate tip that allows you to adjust the width and intensity of the writing depending on the pressure and angle. 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 revolutionary nib of the Air, unlike conventional roller balls, is pressure sensitive, meaning that it gives a writing experience and differentiating line width similar to that of a fountain pen.
