Innovative and proven writing instruments for everyday use. The company Pentel was founded in 1946 and initially focused on the production of watercolor and oil paints, as well as drawing pencils for kindergartens and schools. Numerous achievements in the world of writing and painting products are thanks 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 been continuously working on new and improved developments that make our daily lives easier, especially in writing, drawing, and painting. In 1977, the successful company also entered Switzerland.
