Diplomat Aero Rollerball Pen - Factory

Diplomat Aero Rollerball Pen - Factory. The Aero Collection comes with smooth lines and streamlined body. The writing tools will allow you to feel the legacy of the Zeppelin. These writing tools feature full aluminium casing, anodized surfaces and grooves on the barrel and cap. A stylish pen with high functionality.

Please note: The Aero pens are anodized. During the anodization process, the raw aluminum parts are placed on a metallic appliance. This is necessary to start the electrolytic process, which always needs a direct current to bring the color into/onto the Aluminium. During the anodizing process at this metallic appliance flows the direct current. The appliance makes it impossible to start the anodizing process at this part. So this leads to the metal-looking stripes inside the cap or barrel.
