Pen companies and ink companies sometimes make pens and inks exclusively for sale at a particular pen show. My beloved Edison Comet is one of a limited numbered run of fifteen pens made by Brian and the terrific folks at Edison Pens in Huron, Ohio. Today’s ink was produced exclusively for the 2023 Washington DC Fountain Pen Supershow (often called the DC Supershow). It is ossicle the largest pen show in the world, though if you’re in the US, there is a yearly calendar of pen shows throughout the year and around the country.
