## Overview

The Uni-Ball UBA-188-M is a 12-pack of red gel pens featuring a 0.5mm fine tip with a frictionless metal ball for smooth, leak-free writing. Powered by Uni-Ball Super Ink, these pens offer waterproof, fade-resistant, and acid-free ink that bonds permanently to paper fibers. Designed for professionals who demand precision and reliability, the pens provide variable line thickness controlled by pressure, all housed in a sleek, comfortable design perfect for everyday use.

## 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. Red Ink in a Box of 12.

## Features

- The freedom of a fountain pen without leaking: the unique metal ball of this model moves without friction, no matter what angle the pen is held.
- The ballpoint pen is filled with Uni-Ball Super Ink, an advanced ink formula that bonds to the paper fibres. Never fade, waterproof and acid free.
- Lower pressure creates a thinner line as the ink is transferred directly over the ball. With stronger pressure, more ink flows around the ball and the line becomes thicker.
