## Overview

The uni-ball AIR Micro 0.5mm rollerball pen features a pressure-sensitive nib that varies line width for expressive writing, combined with Uni’s Super Ink that is water, light, and tamper-resistant. Its innovative acetal plastic-encased metal ball ensures smooth ink flow, delivering a premium fountain pen-like experience in a convenient 3-pack of black pens.

## 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.

Review: I love pens and have many, this writes as beautifully as an ink pen. Great find. - Initially the wrong pen was sent, the correct one was sent without question, excellent customer service! The pen itself is lovely, a nice find and I’ll definitely be a return customer.
Review: Great switch from fountain pen - Finally a ball pen / biro which feels like and writes like a fountain pen. Looks elegant Writes neat Very fine 0.5 mm tip Literally writes smoothly on anything Till the last drop of ink no issues Might switch from my parker fountain pen to this one for good

## 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.
