In 1900 the Zeppelin airship began its first test flight under the aeronautical leadership of Earl von Zeppelin. Based on this event and the design of the airship Diplomat introduces the Aero pen to the market. The Diplomat Aero is characterized by groove-like depressions on the barrel and cap which lends the pen next to its classic form a modern spirit. The Diplomat Aero is made of anodized aluminum and is especially designed ergonomically. The clip harmonises well with the shape of the Diplomat Aero.
The mechanical pencil uses 0.7mm leads.
