Uni-ball Air Micro Rollerball Pen

The Uni-ball Air is a specialized rollerball pen manufactured by the Mitsubishi Pencil Company. Known for its unique tip that adjusts ink flow based on writing pressure, it provides a writing experience similar to a fountain pen but with the convenience of a modern rollerball. The brand's products are primarily manufactured in Japan, maintaining a reputation for high-quality precision engineering in the stationery industry.

The Uni-ball brand originated in Japan under the Mitsubishi Pencil Company, which was founded in Tokyo in 1887. While they share the 'Mitsubishi' name and logo with the famous industrial conglomerate, they operate as a completely independent entity. Today, it remains one of the leading global stationery brands, managed directly by its parent company in Japan with various international distribution partners.
