"Science" Standard Roller Ball Pen, a design inspired by Leonardo Da Vinci, comes from ACME Studio's Standard Roller Ball Pens. The design is based on the many sketches of Leondardo's architecture, science including his iconic Vetruvian Man based on his studies of human anatomy. The pen comes with one black roller ball refill. Artist's signature is engraved on the cap band and "ACME" is on the clip. The pen is presented in a ACME metal box with a black sleeve and ACME literature.
