The Faber-Castell Essentio rollerball in Black Carbon features a resin over carbon fiber body, and an ergonomic grip section that makes it the perfect pen for the office or for long writing sessions. The Essentio fountain pen was formerly called the Basic.
The Essentio has chrome-plated accents and clip, and the spring-loaded clip can easily slip onto a shirt pocket or notebook and holds the pen securely.
