Leonardo Officina Italiana is known for making bespoke pens using different materials in limited runs. One of the most recent is the Leonardo Momento Zero Grande LeonArco Gold Amethyst (also known as the Purple Arco), a limited-edition, made-to-order pen that is fashioned from pure celluloid assembled in layers and manually lathed. The result is a gorgeous mix of gold and lilac in a pattern that is unique in every pen. 

This design is only produced upon pre-ordering on the Leonardo Officina Italiana website, but what we have for sale is a very unique new-old-stock Arco Gold Amethyst in the Momento Zero—not Momento Zero Grande—size. This was requested by the original owner as they preferred a mid-size unit that fills with a captured converter. This makes this pen a 1 of 1. It carries a gold M nib and comes with its box, papers, and its ink bottle. 

Length capped: 14 cm.
