Model  D40328023 Steel Nib

The Diplomat Aero Rhomb reimagines the brand’s celebrated Aero design with a bold geometric twist. Its full aluminum body is

enhanced by a circular guilloché engraving that catches the light and creates a refined, contemporary texture. Finished in polished

chrome with matching trim, the pen balances modern sophistication with the streamlined form inspired by the Zeppelin airship that

defines the Aero line.

Equipped with Diplomat’s finely crafted stainless steel nib, the fountain pen delivers smooth, controlled writing with remarkable reliability.

The Aero Rhomb is also available as a twist-action ballpoint, a capped rollerball, and a precise 0.7 mm mechanical pencil—making it

a versatile choice for every writing style.

Since 1922, Diplomat has produced writing instruments in Germany with uncompromising attention to detail, using time-honored techniques

to ensure durability and elegance. The Aero Rhomb continues this legacy, uniting heritage craftsmanship with contemporary design.
