About us

Mitsubishi Pencil’s vision is to become The World's Most Expressive Innovation Company,
inspiring individuality and creativity through our products and our belief that
everyone is unique in their own way.

We have collaborated with numerous artists and fashion brands, creating writing instrument products such as uni, uni-ball, and POSCA that serve as art tools to unlock creative expression.

As a wholly owned subsidiary of Mitsubishi Pencil, Unicosmo carries forward this philosophy into the cosmetics field.
We develop and manufacture pen-type cosmetics as tools to bring out each individual’s unique beauty.
