The company Pentel was founded in 1946 as "The Japan Stationary Corporation" in war-torn Japan, initially focusing on the production of watercolor and oil paints as well as drawing pencils for kindergartens and schools. Many achievements in the world of writing and painting products are attributed to its own research and development laboratory. Examples include the first 0.9 mm fine lead for mechanical pencils, the first fiber pen "SignPen," the first rollerball pen "Ball Pentel," and the first correction fluid with a writing tip instead of a brush. For over 70 years, Pentel has continuously worked on innovations and improvements that make our daily lives easier, especially in writing, drawing, and painting.
