This black and white marbled limited edition Diplomat Aero fountain pen features a Zeppelin-inspired aluminum body with groove-like depressions on the barrel and cap. The unique pattern is made using a hydro dipping marbling technique - the swirling color dyes are floated on the surface of a solution, then each pen is dipped in, transferring the pattern onto the body of the pen. A protective coating is then placed on the marbled pen. No two are exactly alike!

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

Due to the unique manufacturing process, there is at least one point on every pen where a small gap or overlap in the pattern could occur. These vary in severity, location, and subtlety and are to be expected with this Volute design.

Here's an explanation from Diplomat on how this unique finish is applied:

Always looking for surprising and innovative effects for our range, Diplomat is proud to propose the new Volute.

Aero Volute is the result of our research for possibilities to apply detailed and colorful decoration on our metal pens.

For this, we used Hydro dipping or so called water transfer printing technology. This technique made big evolutions for the last years and is used mainly today for personalization, not in industrial series.

As you can see with this link for examples video, painted decoration is applied by water solution.

A film with the decoration to be transferred is carefully placed on the water’s surface in a dipping tank. This clear film is water soluble and dissolves after applying an activator solution.

Once dipping is begun, the surface tension of the water will allow the pattern to curve around any shape. The ink adheres and will not wash off.

In order to have good quality and resistance there are some preparation steps of the surface and finishing steps too, using appropriate clear lacquer. Even more, a real know how for the use of the activator, a perfect dipping technic are required….all this for an amazing result full of colors and details.

We chose this Volute pattern to demonstrate the quality of the details, the respect of the shades of black and provide to the Aero a real different personality.

In a reference to smoke volutes, this aerial design fits the spirit of Aero.

Not used in our writing instrument industry, this kind of decoration and technology enhanced Diplomat modernism through our Flagship Aero and our capacity to surprise our partners and consumers.
