Each Diplomat Aero Fountain Pen includes a pen case and a matching color ink bottle. Make your writing complete with the Diplomat Sets in Aero Orange color.

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.
