## Overview

The uni-ball AIR 0.7mm Medium Rollerball 5-pack offers a revolutionary pressure-sensitive nib that mimics fountain pen line variation, combined with Uni’s tamper-resistant, water and light-proof Super Ink. Encased in smooth-flow acetal plastic, these pens deliver a flawless writing experience in black, blue, and red—ideal for professionals who demand precision, security, and style in every stroke.

## 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 five gel ink rollerball pens, two with black, two with blue and one with red ink.

Review: Brilliant pen . - Great service from.desertcart , delivery on time . Uni ball Air pens are amazing, to active a fountain pen writing from.a roller ball is brilliant. I tired so many different pens over the years this is the best .
Review: Like Writing With a Fountain Pen. - Originally bought a couple of these at an airport, along with a notepad. Liked them so much I picked up a bunch more. The fine-nibbed ones scratch a little at first, but persevere and they quickly become smooth and joyful to write with. The medium ones write beautifully from the get-go. The ink has intense colour but like fountain pens, it stays wet for a few seconds, so might cause left-handers a bit of trouble. If you enjoy writing and value the experience of writing, these are ideal.

## 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).
- 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 pack contains five pens. Two with black, two with blue and one with red ink.

### ⭐⭐⭐⭐⭐ Like Writing With a Fountain Pen.

Originally bought a couple of these at an airport, along with a notepad. Liked them so much I picked up a bunch more. The fine-nibbed ones scratch a little at first, but persevere and they quickly become smooth and joyful to write with. The medium ones write beautifully from the get-go.

### ⭐⭐⭐⭐ Watch out for the paper you use.
*by Z***S on 12 January 2026*

This was one of my favourite pens to write with. However, you do need to be mindful of the paper you use, as the ink can sit on the surface and smudge on certain types.
