Uni-Ball UB-188-L Air Rollerball Pens for Super Smooth Handwriting

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 pen's unique metal ball is held in a plastic surround, allowing it to move without friction when the rollerball pen is held at an angle. 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. It is also fade resistant, water resistant, and acid-free. Writing with light pressure will give a finer line as the ink is transferred by the ball itself, while 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, depending on the pressure applied, making the pen perfect for writing or calligraphy. The pen offers a sleek, elegant look and feel that is comfortable and easy to grip. The capped top stays put, ensuring that this pen will never leak in your pocket. Available in a box of 12 with black ink, the Uni-Ball Air Medium combines the freedom of a fountain pen with the security of a roller-ball, without the risk of leaks.
