Uni Pin Fine Line drawing pen

The Uni Pin Fine Line is a high-quality drawing pen produced by the Mitsubishi Pencil Company. Known for its water and fade-proof pigment ink, it is a staple for illustrators, architects, and artists globally. The brand 'Uni' (often referred to as Uni-ball) has its roots in Japan, where the Mitsubishi Pencil Company was established in the late 19th century.

While the company is headquartered in Tokyo, Japan, manufacturing is distributed across several East Asian facilities. Many Uni Pin pens, such as the one pictured, are manufactured in Vietnam, though some components or specific models are also produced in Japan. The Mitsubishi Pencil Company remains an independent entity and is not affiliated with the Mitsubishi Group of companies (which includes the automotive and electronics divisions), retaining its position as a specialized global leader in writing technology.
