Uni-ball is a pen brand by Mitsubishi Pencil Company, one of Japan's most respected writing instrument manufacturers. The Air is one of their most distinctive rollerballs, built around a tip design that sets it apart from anything in its category.
Where most rollerballs hold the ball in a rigid metal surround, the Air uses an acetal plastic surround that allows the ball to move freely. The result is a line that responds to pressure and angle the way a fountain pen does, thickening with a heavier hand and thinning with a lighter one. It writes smoothly at any angle, making it as comfortable for journaling and everyday writing as it is for sketching or loose lettering. The ink is Uni's Super Ink, a pigmented liquid ink that is water-resistant, fade-proof, and acid-free, so it holds up in notebooks meant to last.
