uni-ball Eye Micro rollerball pen

The uni-ball Eye Micro is a world-renowned rollerball pen celebrated for its smooth ink flow and 'uni-flow' system. Originally launched in 1994, it has become one of the most successful writing instruments globally, favored by professionals and students alike for its waterproof and fade-proof pigment ink.

The brand is owned by the Mitsubishi Pencil Company, which, despite the name, is entirely independent of the larger Mitsubishi Group conglomerate. The company's history dates back to 1887 when it was founded in Tokyo as a small wooden pencil manufacturer. Over the decades, it transitioned into performance writing tools, revolutionizing the market in 1979 with the first liquid ink rollerball under the 'uni-ball' name.

Today, the brand remains firmly rooted in Japanese engineering. While it utilizes a vast network of international subsidiaries for distribution—such as Mitsubishi Pencil Company UK for the British market—the core manufacturing of the uni-ball Eye series continues to take place in Japan to maintain strict quality standards.
