Description The Diplomat Aero ballpoint in Red features a red anodized aluminum body, accented by matte silver clip and trim. The Diplomat Aero ballpoint uses a twist mechanism to extend and retract the ballpoint refill. The Diplomat Aero was created to capture the feel of the Zeppelin airships of the early twentieth century. The rigid exterior of those Zeppelins is brought to mind with the shape and exterior grooves on the pen. The Diplomat Aero ballpoint accepts Parker style ballpoint refills. Some color options may take 7-10 days for delivery.
