## Overview

The uni-ball UB-188-L Rollerball Pen combines the luxurious feel of a fountain pen with the dependable, leak-free performance of a rollerball. Featuring a 0.7mm medium nib and Uni Super Ink, it delivers smooth, fade-resistant, and water-resistant red ink that adapts to your pressure for perfect line variation. Packaged in a convenient box of 12, this pen is designed for professionals who demand precision, style, and reliability in every stroke.

## 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. Red Ink in a Box of 12
