## Overview

The Uni-Ball AIR Micro 0.5mm rollerball pen features a pressure-sensitive nib that varies line width like a fountain pen, encased in acetal plastic for smooth ink flow. It uses Uni's Super Ink, which is water, light, and tamper-resistant, ensuring secure, professional writing. This pack of three blue pens combines comfort, precision, and durability for the discerning professional.

## 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 0.5mm ball delivers a line width of between 0.28mm and 0.45mm (dependent on pressure).
- 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.
- Pack contains 3 Blue inked pens.
