The Pilot CON-20 was a aerometric, or pump-style, fountain pen converter sold with some Pilot pens. The basic construction of the converter was a rubber bladder inside of a metal shell with a press plate on the side. You’d submerge the bottom of the converter in ink, press the plate and the ink would bubble. After you would let go and the spring-loaded press plate would suck ink into the bladder making for a cheap, but not very good converter.
The CON-20 was included with the Pilot Metropolitan and some other affordable pens for a time, but in 2017 it was discontinued. The CON-40 replaced it.
This converter is often confused with the Pilot Metropolitan converter, which is more commonly known as the CON-B.
