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, 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.
