Uni-ball and Uni are brands of pens and pencils,[1] made by the Mitsubishi Pencil Company Limited (三菱鉛筆株式会社, Mitsubishi Enpitsu Kabushiki Gaisha, TYO: 7976) of Japan. The brand was introduced in 1979 as a rollerball pen model, then expanding to the rest of Mitshubishi Pencil products.[3]

Mitsubishi Pencil Company distributes products in over 100 countries through subsidiaries, such as Mitsubishi Pencil Company UK. Distribution in the United States, Canada and Mexico is by uni-ball's North American Corporation in Wheaton, Illinois. In Germany they are sold by Faber-Castell, in the Persian Gulf and the Middle East by Hoshan Pan Gulf,[4] and in India by Linc Pen and Plastics Limited (LPPL).[5][6] Despite its naming and the near identical logomarks, Mitsubishi Pencil Company is unrelated to the Mitsubishi Group,[7] and has never been a part of their keiretsu.[8]


The company was founded in Tokyo by Niroku Masaki in 1887,[9] as the "Masaki Pencil Manufacturing Company".[2] It wasn't until after the World War II that the company became "The Mitsubishi Pencil Company".[2]

Masaki Pencil started to export its products, first to Mexico in 1927, expanding to other markets including India, Egypt, Portugal, Argentina, Belgium and Netherlands. At the end of World War II, the company introduced the "9800" pencil. In 1959, Mitsubishi released its first ballpoint pen, while its first mechanical pencil was launched in 1961.[3]

In 1966, they began creating performance pens and by 1979 they developed the first "Uniball" rollerball pen,[9] which was the first ballpen with water-based ink and metallic tip. This pen would be a great success in Japan and North America. One year later, the company launched the "Paint", an oil-based marker.[3]

While mainly focused on making pens, in 2008 they developed a new mechanical pencil that rotated the graphite lead every time it is lifted from the page to sharpen it into an even cone shape. This line of pencils is named as Kuru Toga.[10]


Uni M7-552 mechanical pencil.

Although Mitsubishi Pencil started as a wooden pencil manufacturer, the company is no longer specialised in that product, focusing on mechanical pencils instead. Uni-ball's writing implements brands include Jetstream (ballpoint pens); Vision, Air (rollerball pens), Signo (gel pens), Onyx, KuruToga (mechanical pencils),[11] Paint, Posca, Chalk, Prockey (marker pens).[12]
