Argentum Fountain Pen - 925 Sterling Silver

This pen comes with the 18K Shogun Nib. 

The Argentum Fountain Pen is a 1-of-1 masterpiece crafted in collaboration between Wancher Pen and Argentinian Artisan Ariel Kullock. There will never be another Argentum Fountain Pen like this, which we have released in time to celebrate the upcoming Argentinian Independence Day on July 9, 2026. 

Milonga in Silver

The inspiration behind Argentum fountain pen lies in one of Argentina's most enduring cultural traditions: the Milonga. Long before Tango became known around the world, Milonga brought together music, dance, and social gatherings that embodied the rhythm and spirit of everyday life.

The word "Milonga" can refer to three different things - a social dance gathering, a genre of music, and a style of dance that predates the more widely known Tango. 

The artisan Ariel Kullock has depicted a classic Milonga from 20th Century Argentina on the entirety of the sterling silver fountain pen. 
It is the confluence of all these vibrant and unique facets of Argentinian culture, and the fact that it was depicted using acid on the 925 Sterling Silver body of a fountain pen that encapsulates the beauty of the Milonga - an all-encompassing feeling or zest for life that cannot be denied by any who behold it. 

A Dance Across the Pen

The Argentum Fountain Pen is crafted from solid 925 sterling silver and transformed through meticulous acid etching by master artisan Ariel Kullock. The pen is simultaneously a testament to craftsmanship, and the beauty of writing instruments, which makes its source of inspiration all the more fitting: The Milonga. 

On the cap, an Argentinian musicians animate the cap in finely etched silver, evoking the lively atmosphere of an early twentieth-century dance hall.

The body of the pen shows two couples dancing in tight embraces with a dark background made by melting a portion of the silver with acid and allowing the rougher texture to remain for a noticeable contrast with the smooth silver sheen of our dancers. The dancefloor beneath them completes the setting, as it forms a mosaic of the same tilework that can be found on many floors of 20th Century Argentinian dance clubs. 

The Art of Acid Etching

Acid etching is a craft that demands absolute precision. Unlike engraving, every decision is permanent. Once the silver is exposed to the acid, there is no opportunity to erase or correct a line. Each design must be carefully envisioned before the first mark is ever made.

Once the the design finalized, the artisan must seal the areas of the pen which he does not want to be affected by the acid. The sterling silver surface is meticulously masked before Ariel Kullock draws the composition directly onto the pen by hand. Each and every single line is one man's creation. Working across its curved surface requires exceptional control, allowing every line to flow naturally around the form of the writing instrument. 

After the design has been drawn onto the silver surface, the entire pen is immersed in a literal bath of acid. It is at this point of the process that you can distinguish between a novice and a master, remove it too soon, and the design remains incomplete; leave it too long, and the silver loses the delicate balance that defines the finished work.

The master, however, waits the exact right amount of time, and removes it from its acid immersion when the design is fully realized. This is the magic of sterling silver, acid, and artistry combined.
