The Pilot CON-70 is a high-capacity converter made for compatible Pilot fountain pens. Unlike a standard twist converter, it uses a push-button piston mechanism that draws ink into the chamber with repeated presses, giving you more ink capacity for longer writing sessions.
It is a good choice for Pilot pens that can accommodate the larger converter, especially if you prefer bottled ink and want to refill less often. The clear body lets you see your ink level at a glance, while the metal-tone trim keeps it looking clean inside the pen.
The CON-70 is compatible with select Pilot fountain pens, including models such as the Custom 74, Custom Heritage 912, Custom 823 where applicable by market, Justus 95, and other Pilot pens designed to fit the larger converter. It is not compatible with all Pilot pens, including the Metropolitan, Prera, E95S, or pens that only accept smaller converters such as the CON-40.
Use with bottled fountain pen ink only. Fill by inserting the converter into the pen, dipping the nib fully into ink, and pressing the button several times until the chamber fills.
