I liked this converter until I cleaned out the pen. It's a piston converter, and
it held a decent amount of ink, for a converter. I don't know if it makes a
difference, but I used the converter in an AG Spalding fountain pen.
However, when I started to clean the pen, I discovered that there was a lot of
ink ABOVE the piston. There is no reason for ink to be up there, and it was
almost impossible to clean it out of the converter. I still haven't managed it.
I'm not sure if I want to bother refilling this cartridge and give it a second
This is a great converter. It fits my Franklin Cover Fremont fountain pen like
a glove. It is pretty standard, the ink does not leak. I read many suggestions
online that a Standard International Cartridge Converter by Schmidt fitted my
fountain pen but I decided to go with the Monteverde converter and it worked!.
I Guess they are similar although have not tested it personally.
