Uni-ball is a global brand of Mitsubishi Pencil, which was founded in Japan in 1887 under the name Masaki Pencil Manufacturing Company. Having launched the world's first rollerball pen with a metal tip and water-based ink in 1979, the brand has maintained its position as a pioneer and leader in the rollerball category ever since.

The brand's most distinctive feature is the Uni Super Ink technology it has developed. This ink ensures that writing remains resistant to water, the fading effects of light, and chemical substances; this feature offers a practical advantage, especially in signing and writing official documents, by reducing the risk of forgery and fading.

The collection includes Eye series classic rollerball pens (in various tip sizes), Signo/Um-153 series security ink signature pens, Signo Noble Metal gel pens in gold and silver tones, and Signo Angelic gel pens in pastel colors. This wide range caters to different areas of use, from daily writing and formal signature needs to decorative note-taking and special projects like business cards/greeting cards.
