## Overview

The uni-ball AIR Micro 3-pack features a revolutionary pressure-sensitive 0.5mm rollerball nib encased in acetal plastic for smooth, variable line widths. Equipped with Uni’s Super Ink, it offers water, light, and tamper resistance, ensuring your signatures and notes remain pristine and secure. This set includes black, blue, and red pens, making it the ideal choice for professionals who demand precision, reliability, and style in their writing instruments.

## 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: Great Pens - Love these pens I have had a few packs of them and I use them all until they are finished. I write my signature a lot on various forms and fountain pens always seem to smudge so these are prefect. the nib is not fine but not thick and produces a nice write. Very happy. Will continue to purchase.
Review: Better than I imagined - Time and time again I reach out for these pens; they are a delight to write with.

## 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 one of each of the following coloured inked pens: Black, Blue, and Red.
