Diplomat Aero Rhomb Pen

A refined twist on a signature design, the Diplomat Aero Rhomb stands apart with a smooth, streamlined surface in place of the Aero’s traditional grooves. Guilloche engraving adds subtle, concentric rings to the polished aluminum barrel and cap, creating a tactile elegance you can both see and feel. Chrome trim and a matte black grip complete the modern silhouette. Sleek, sculptural, and quietly bold—this Diplomat Aero brings understated sophistication to every word. Rollerball or Ballpoint.
