## Overview

The uni-ball AIR Micro 4-pack features 0.5mm pressure-sensitive rollerball pens with a unique acetal plastic-encased metal nib for smooth ink flow and dynamic line width. Equipped with Uni’s Super Ink, these pens offer water, light, and tamper resistance, ensuring your writing stays sharp and secure. Perfect for professionals seeking a fountain pen feel without the fuss, this set includes two black and two blue pens designed for ambidextrous use and long-lasting performance.

## 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. This set contains four gel ink rollerball pens, two with black and two with blue ink.

## 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.
- This set contains four pens, two with black and two with blue ink.
