Let it inspire you to explore your creativity through art, lettering, and journaling, turning every stroke into an act of self-expression, reminiscent of precious ore. 

The Madison Prospector (black) pen comes with a choice of Steel or Gold Clip. The price indicated is just for the pen body that includes a cap & barrel, with a converter. Choose one or more of your preferred Nib Unit(s) to complete your Fountain Pen.

Important Notes:

·       Avoid India inks to prevent clogging the ebonite feeds; use fountain pen-friendly inks only.

·       If selecting the Zebra G nib assembly, we recommend adding a nib-block kit if you don't already own one. Download our maintenance guide to easily disassemble and reassemble your flex nib & feed as needed. Note: The nib-block kit does not accommodate size 6 nibs; please use the provided grip tool in the kit, for disassembling size 6 nib units.
