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 writing and drawing product world are thanks to its own research and development laboratory. Examples include the first 0.9 mm fine lead for mechanical pencils, the first fiber tip pen "SignPen," the first gel 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.
