Edison Comet Fountain Pen - Cobalt Magma
This Edison Comet fountain pen is made of a flecked blue and red resin, with a silver clip and a translucent red finial, and a #6 polished steel nib engraved with the Edison logo. It accepts a standard international converter (included) or short standard international cartridges, or can be converted to eyedropper fill.
All Edison pens are handmade in Milan, Ohio by Brian Gray. We do our best to photograph the pens to show how they will appear in person, but due to the nature of the material, expect some variation in the pattern from what you see here.

We do our best to photograph the pens to show how they will appear in person, but due to the nature of the material, there will be some variation in the pattern seen here. This adds an element of uniqueness to the pen, with no two patterns being exactly the same. We cannot honor special requests.
Note: Edison is in the process of updating their nib designs; our stock is currently mixed and what you receive may or may not match what is pictured. We are unable to honor special requests.
