The company Pentel was founded in 1946 in war-torn Japan and initially focused on producing watercolor and oil paints as well as drawing pencils for kindergartens and schools. Many 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 ink roller "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 innovations and improvements that make our daily lives easier, especially in writing, drawing, and painting. In 1977, the successful company also entered Switzerland.
