The Pilot Con-70 converter is pretty cool. It's kind of this hybrid button/vacuum filling cartridge/converter that only fits some of the larger Pilot pens, like the Custom 74 (a favorite of mine), the Justus 95, and the Metal Falcon. Because so few pens use it and it is so different than most other types of converters, it can be confusing to fill if you don't quite know what to do. So that's exactly why I made this video!
