Uni-Ball UB-188-L Air Rollerball Pens. Premium 0.7mm Medium Nib. Fountain Pen-like Writing. Fade and Water Resistant Uni Super Ink. Box of 12 Black Pens

Experience the elegance of a fountain pen combined with the security of a roller-ball, all while avoiding any leaks with the Uni-Ball Air Medium. This unique pen features a metal ball encased in a plastic surround, allowing for smooth movement without any friction, especially when the pen is held at an angle. The pen is equipped with Uni-Ball Super Ink, an advanced formula that binds effectively to paper fibers and resists fading, water damage, and acidic substances. Additionally, this ink is resistant to chemicals that typically remove dye-based ink from checks.

By adjusting the pressure applied while writing, you can control the thickness of the line produced by the pen. Light pressure results in a finer line, as the ink is delicately transferred by the ball itself, while firmer pressure allows the ink to flow more freely around the ball for a thicker line. With an average line width ranging from 0.355mm to 0.55mm, the pen is versatile enough for various writing tasks, including calligraphy.

Not only does the Uni-Ball Air Medium deliver exceptional performance, but it also boasts a sleek and elegant design that offers a comfortable grip. The secure cap ensures that the pen will never leak in your pocket. Each box contains 12 pens with black ink, providing you with a reliable and stylish writing tool for any occasion. Enjoy the freedom and flexibility of a fountain pen combined with the reliability and convenience of a roller-ball – all without the worry of leaks.
