What comes in the box with the Rhomb Chrome Aero?
The pen ships in a case that holds three writing instruments. Inside you will also find a converter, two standard international ink cartridges, and a warranty card. That means you have everything needed to fill the pen from a bottle or to start writing with a cartridge straight away.
What nib widths are available for this fountain pen?
The stainless steel nib is offered in extra fine, fine, medium, and broad. All four widths are available on the Rhomb Chrome model, so you can match the nib to your writing style or paper before you order.
How does the cap close, and will it stay shut in a bag?
The cap closes with a soft sliding click. Diplomat describes this as an exclusive closing system. That positive click confirms the cap is fully seated, so the pen is secure when carried.
What warranty covers this pen, and where is it made?
The Diplomat Aero carries a five-year manufacturer warranty, and a warranty card is included in the case. The pen is made in Germany at Diplomat's production site in Cunewalde, Saxony. Diplomat has produced writing instruments in Germany since 1922.
