Nib Size Nib Guide

The Diplomat Aero Rhomb Flame presents a striking new interpretation of the Aero collection, replacing the iconic Zeppelin-inspired grooves with an intricate rhomb-pattern guilloché engraving. Crafted from solid aluminum, each pen is individually hand-torched to create a mesmerizing spectrum of blue, bronze, gold, and violet tones. Because the flame treatment is applied by hand, every pen develops its own unique color pattern, making each writing instrument truly one of a kind.

The Aero has a satisfying soft sliding click cap, that posts securely onto the barrel when writing. It features a smooth writing #6 JoWo silver stainless steel nib, a matte black grip and chrome trim, and fills via standard international cartridge/converter (both are included).

Handcrafted in Germany since 1922, Diplomat writing instruments are renowned for their exceptional quality, precision engineering, and timeless craftsmanship. The Aero Rhomb Flame combines innovative surface engraving with a hand-applied flame finish, resulting in a bold writing instrument where no two pens are exactly alike.

Frequently Asked Questions

How do I use this pen with ink cartridges?

A cartridge is small, disposable, sealed plastic reservoir that holds fountain pen ink. These come pre-filled with ink, and typically you just push to insert them into place and you'll be ready to write!

This pen uses standard international ink cartridges, a common size which is available in many colors from various brands.

You can learn more about how to actually install an ink cartridge on our blog, or in this video tutorial:

How do I use a converter?

A converter goes in the place of where the ink cartridge would normally go. From there, you can fill your fountain pen from bottled ink.

A converter is a detachable and refillable ink reservoir that allows you to use bottled ink in a cartridge-accepting pen. Typically you will install the converter into the grip section, dip the nib/feed into the ink, and twist or pull the converter knob to draw ink into the converter.

We have a great video showing how to use a converter here:

How do I clean this fountain pen?

It mostly comes down to flushing out the pen with water, and sometimes a little bit of pen flush if the ink is really stuck.

We put together a blog post with step-by-step instructions, or you can watch the video here:

We recommend a good cleaning every 2 weeks, and any time you change ink colors. Water will usually do the trick, but we recommend you use our Goulet Pen Flush if the ink has been left in the pen for a while and could have dried up, or when you’re switching ink colors.
