## Description

Pack of 4 Blue, Green, Pink and Orange Barrel Uni-Ball Air Pens from Uni-Ball.

Review: Perfect, but - Those pens are amazing, no smudges, quick dry. Perfect is the word to describe them in my opinion, but received wrong ink colour.
Review: Cool pens - I love the way these pens write, they come in cool different colours and last a while. Recommended

## 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.
- Each pen contains black ink and has a 0.5mm tip that writes a slightly finer line than the medium.
- The Air pen contains Uni-Ball’s Super Ink which is not only water and light resistant "Tamper-Resistant", meaning that the ink cannot be washed off using chemicals and solutions used by people to fraudulently modify documents.
- When writing with less pressure you will receive a finer line as the ink is transferred by the ball itself, whereas pressing a little harder gives a thicker line as the ink is able to flow freely around the ball.
- Unlike other rollerballs, the Air features a ball which can move freely within a plastic surround, resulting in far less friction when the pen is held at the right angle.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Perfect, but
*by M***L on 21 February 2025*

Those pens are amazing, no smudges, quick dry. Perfect is the word to describe them in my opinion, but received wrong ink colour.

### ⭐⭐⭐⭐⭐ Cool pens
*by C***R on 8 December 2023*

I love the way these pens write, they come in cool different colours and last a while. Recommended

### ⭐⭐⭐⭐ Remember they're all black ink
*by N***L on 30 April 2020*

Yes I did the classic and looked and the picture and not the title. Yes they are lovely and colourful looking pens but they are all black ink. My fault there so no stars deducted for that. They do write incredibly smoothly, and they are pressure sensitive so the harder you press, the thicker your line. I've quite heavy handed and have been working hard to put less pressure on. But even when trying to be as light as possible, I do find the ink takes a little longer to try than other pens. I do get the occasional pen smear on my hand on slight smudge on the paper if I'm writing quickly. I probably wouldn't use these for heavy note taking for this reason, but for small amounts of writing they're lovely. My final point, and this may just be my taste, but they were capped in mismatching colours like in the picture. The thought of what kind of a monster would do this is quite distressing. But I quickly resolved it and they now live with their correct lids in a neat line at stationery village.
