## Overview

The Uni-Ball Air Micro Nib Rollerball Pen combines the elegance of a fountain pen with the reliability of a rollerball. Featuring a frictionless metal ball for smooth ink flow, it uses Uni-Ball Super Ink that is waterproof, fade-resistant, and chemically secure. Its fine 0.25-0.45mm line width is perfect for precise writing, while the ergonomic, leak-proof design ensures comfort and portability. Available in a convenient 12-pack of black ink pens, it’s the ultimate tool for professionals who demand precision and style.

## Description

The Uniball Micro-Air ballpoint pen gives you the freedom of a fountain pen with the security of a roller-ball with no leaks. Unlike other rollerballs, the Air’s metal ball is held in a plastic surround, allowing the ball to move without friction when the pen is held at an angle. It is filled with Uni-Ball Super Ink, an advanced ink formula that bonds to paper fibers. It is resistant to chemicals that wash dye-based ink from checks. Super ink is also fade resistant, water resistant, and acid free. Applying 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 Micro-air pen will give you a finer line width between 0.25mm - 0.45mm, perfect for technical writing or small printing. The sleek, elegant look and feel that is comfortable and easy to grip, and the capped top stays put and ensures that this pen will never leak in your pocket. Black Ink in a Box of 12.

Review: Super Slim Red Line- Super Demure - These are another one of my favorite red felt tip pens when I'm not using Italy made ones, super slim line- super demure
Review: Makes fountain pens more everyday - Changing reading to 5 starts. While the ink doesn't dry quickly, the pen is easy to use. These are far less messy that a "real" fountain pen. I like them and will buy again.
