The Uni-Ball AIR 0.7mm Medium Rollerball pen features a pressure-sensitive nib encased in acetal plastic for a smooth, variable line width between 0.35mm and 0.55mm. Lightweight and designed for comfort with a soft grip and ambidextrous use, it delivers vibrant blue hybrid ink that dries quickly, making it ideal for professionals seeking precision and style in every stroke.

## Description

Description 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

- 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).
