The Aero Collection is distinguished by its smooth lines and streamlined body. Feel the legacy of the Zeppelin and give height to your narratives. Diplomat writing instruments have been crafted using traditional methods since 1922. A combination of exceptional German know-how, high-quality materials and a dedication to offer only the best products has allowed Diplomat Pens to stand the test of time. The fountain pen is carttidge/Converto fill and is available with a 14kt Gold or steel nib in M, F, XF, and B widths. A convertor is included. The collection is completed with a matching capped rollerball, twist-activated easyFLOW ballpoint pen and a .7mm mechanical pencil.
