## Overview

The Uni-Ball AIR 0.7mm Medium Rollerball pen features a unique pressure-sensitive nib encased in acetal plastic, delivering a smooth, variable line width between 0.35mm and 0.55mm. Its innovative design ensures increased ink flow with pressure, providing a writing experience akin to a fountain pen.

## Description

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: BEST PEN EVER!! - As RN since the mid 80s, for many years we wrote/documented an enormous amount DAILY, and for me, having a GOOD pen was VERY important. When I tell you that over the years I have tried probably every single, solitary brand of pen available, I am not exaggerating. So to state (without question) that this is the VERY BEST PEN out there is an impactful statement. Not only do they write beautifully & smooth, the color is strong, does not fade, and they LAST FOREVER!! I am STILL using a pen I had used when working at a doctors’s office back in 2017 and it is just NOW running out of ink. That being said, I did retire in 2017 so it has NOT been used as heavily on a daily basis as when I was still actively working, but that’s still an awfully long time! :) Bottom line: If you are passionate about writing with the “perfect“ pen, then you need to try the Uni ball AIR medium.
Review: BUY THEM! YOU WON’T REGRET IT! - I’m an absolute pen snob! I’m constantly trying new pens to find my “go to” pen and I think I FINALLY found the one. These pens are AMAZING! They write super smooth and the ink dries very fast. I personally like blue ink pens, but I like that they have the option for black and red as well. I will definitely be ordering those here soon to have as well. I work in the healthcare industry and yes having to keep track of a cap is difficult, but so worth it when it comes to these pens. - I want to make it clear that I bought these with my own money and my review is my own true feelings of this pen. I was not given these pens to leave a review.-

## 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).
