Rollerball for writing and drawing. Fast-drying gel roller with a push mechanism and metal tip. Made from 54% recycled material. Ball diameter: 0.7 mm, line width: 0.35 mm.

Unlike ink rollers with Free-Ink, EnerGel does not require a regulator to feed and control the ink flow - the ink flows directly from the reservoir to the writing tip, ensuring a consistently smooth writing experience. The products in the EnerGel family offer an ultimate writing feel. Most models are produced with a high recycling content. Innovative and proven writing instruments for daily use. 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 writing and painting product world are attributed to its own research and development lab. Examples include the first 0.9 mm fine lead for mechanical pencils, the first fiber tip 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 continuously worked 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 as "Pentel Papeteriewaren AG.".
