Diplomat Aero Rollerball Pen

Diplomat's latest offering, the 'Aero' features curved lines and a torpedo-shaped body, characterised by the manufacturer as channelling the legacy of the Zeppelin - "give height to your narratives".

The aluminium barrels use an anodized finish and have fluted, grooved depressions running along the full-length of the pen, following the contours of the barrel and cap where they begin to narrow.

Available in black, matt silver, brown, factory and orange.
