## Overview

The uni-ball UB-188-L Air Rollerball Pen features a 0.7mm medium nib with a unique frictionless metal ball that writes smoothly at any angle.

## Description

Enjoy the feel and elegance of a fountain pen with the security of a roller-ball and none of the leaks with the Uni-Ball Air Medium. The Air’s metal ball is held in a plastic surround, allowing the ball to move without friction when the rollerball pen is held at an angle. The ballpoint pen is filled with Uni-Ball Super Ink, an advanced ink formula that bonds to paper fibers. The ink is resistant to chemicals that wash dye-based ink from checks. Super ink is also fade resistant, water resistant, and acid free. Writing with light pressure will give a finer line as ink is transferred by the ball itself, whilst firmer pressure allows the ink to flow freely around the ball for a thicker line. The average line width is between 0.355mm and 0.55mm when varying with the pressure applied, making the pen perfect for writing or calligraphy. The pen also offers a sleek, elegant look and feel that is comfortable and easy to grip. The capped top stays put and ensures that this pen will never leak in your pocket. Black Ink in a Box of 12

Review: My favorite pen - Actually makes my handwriting neater. Very smooth and pleasant to write with. Writes at any angle!
Review: Why? What would you change perfection? - So this is going to come across as way too detailed to come from anyone other than a pen geek - but believe it’s actually a big deal. This is a a different pen than the earlier version with the all black barrel. This striped barrel is bigger, wide than it used to be when it looked like a solid black style. Which means - if the black barrel version fit your hand perfectly, then this one with the striped barrel is going to suck because it’s different enough that it’s hard to write the same way. The ink appears to be the same and the point appears to be the same, but if you can’t hold the pen and write like a normal person - then those things don’t matter - the pen stops being a pen - or more accurately, you just stop using the pen. Which is a terrible terrible result. Please fix this?! Pete
