Company Profile Request update info.

Founded by Niroku Masaki and 10 employees in Shinjuku, Tokyo, Masaki Pencil Manufacturing Company creates pencils of superior quality and style. With those wooden pencils, the uni-ball story begins.

In recognition of a modern need for performance pends, the Mitsubishi Pencil Company (formerly Masaki) releases its first, the “uni-pen” and the “uni-pen Deluxe”. They’re the roller ball pens that start it all.
