Ariel Kullock is an Argentinian innovator, artist, and customizer of fountain pens. Since the 1990s, he has been creating unique fountain pens—starting with modified Parker 45s, later moving on to Parker 51s using new barrels, section parts, custom caps, and fully reimagined Parker 51 “fantasy” pens. This is one of his early pieces. The pen comes with a 1-year warranty and can be tested upon pickup.
