## Overview

The Uni-Ball AIR 0.7mm Medium Rollerball pen features a revolutionary pressure-sensitive nib encased in acetal plastic for ultra-smooth ink flow and dynamic line width. Equipped with Uni's Super Ink, it offers water, light, and tamper resistance, making it ideal for professional document marking. This pack of three vibrant red pens delivers a bold, expressive writing experience that elevates everyday note-taking and editing.

## 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: Parfait, je recommande
Review: I bought these because I was looking for a red pen that didn't feel "scratchy" like standard ballpoints, but I wasn't expecting the unique writing experience the Uni-ball Air offers. It is completely different from a standard G-2 or Jetstream. The "Air" Tip is the real differentiator: The tip is made of acetal plastic rather than the usual metal surround. This does two things: 1. It is incredibly smooth. It glides over paper with zero friction, almost like a felt-tip marker but with the firmness of a rollerball. 2. It allows for variable line width. If you apply light pressure, you get a fine line (approx. 0.3mm). If you press harder or change the angle, the line thickens (up to approx. 0.5mm). It gives your handwriting a bit of character that you usually only get from fountain pens. The Ink: The red is vibrant and highly saturated. It stands out aggressively on white paper, which makes it excellent for grading or marking up documents (my primary use case). It flows "wet," meaning it puts down a lot of ink quickly. The Downside (Why I knocked off a star/What you should know): Because this pen is a "gusher," it is very picky about paper. • On standard copy paper: It works great and dries relatively fast. • On cheaper notebook paper or thin journal pages: You will see significant "ghosting" (seeing the ink from the other side) and occasional bleed-through. If you use a Moleskine or thin planner, this might be too wet for you. Verdict: If you want a red pen that requires zero hand pressure and offers bold, expressive lines, this is fantastic. If you write on thin paper or need a precise, consistent fine line for tiny margins, stick to a gel pen like the Signo 0.38mm.

## 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.
- Pack contains three Red inked pens.
