You don’t want any old pen, you want a reliable pen. A pen that performs 24 hours a day, seven days a week, whatever the occasion, wherever you may be…

Because you don’t just write on paper, with a desk to lean on, at a perfectly upright angle, in dry conditions and with all the time in the world. You write standing up, sideways, upside down, on your hand, on whiteboards, outside in the soaking rain, on a plane at altitude, and in a rush. So it’s no good if your pen works some of the time, and only in ideal conditions.


Uni-ball knows this, and that’s why we pride ourselves on delivering reliable pens that perform all day, every day, whatever you’re doing, wherever you are. We’ve been doing it for more than a century…

In 1887, Niroku Masaki founded a small company in Tokyo making writing tools, this soon became the Uni Mitsubishi Pencil Company. Fast forward to 1979 when the first uni-ball rollerball was created. Its excellent quality and fantastic writing finish made it an instant success. Building on this, uni-ball Eye rollerball was developed and launched in 1994 and is still one of the world’s most popular rollerballs. Why? Because we combine quality, innovation and design to deliver an exceptional writing experience every time.

Our art products are the first choice for creatives. The uni-PIN collection is a favourite of architects, graphic designers, fine artists and illustrators. POSCA paint marker pens are championed by street-artists, sign-writers, fine artists and home crafters alike.

We never stop inventing and innovating to bring you the best and most reliable writing and drawing kit. From superb rollerball and ballpoint pens for school and office handwriting to professional-standard fine-line markers and paint-pens for hobbyist and artists, our pens bring extraordinary performance for everyone everyday.
