This is a Staedtler pen with a unique triangular barrel designed with ergonomics in mind. * Includes company and location names. For those who don't mind. * Almost unused and stored at home, but I'm selling it because it appeared in the "God Pen" series of pen modification videos by professional pen spinner kay on YouTube. He said that pen provides a miraculous fit. * The refill has been replaced with a Pilot one, but the ink is not as vibrant as Acro Ink. * There are some uneven spots on the metal part near the pen tip. Type: Ballpoint pen Ink: Oil-based Features: Single color Barrel color: Dark gray
