The Monteverde Mini Ink Converter is designed to fit most fountain pens that take short standard universal ink cartridges. It has a simple plunger style filling system with an easy to use push/pull action. This mini ink converter does not hold as much ink as a short cartridge, so why would anyone want to use it? An ink converter allows you to use bottled fountain pen ink in a fountain pen that would normally only use ink cartridges. This greatly expands the selection of ink that you can use with your pen, reduces waste and saves a bit of money!
There are several fountain pens and rollerball pens that have a barrel that is too short or too narrow to take a regular size ink converter. This is where the Monteverde Mini Ink Converter comes to the rescue! Fully extended the Mini Converter is only about 2.25″ long. Here it is inside a J. Herbin Rollerball Pen:
It also fits inside the short barrel of the Kaweco Sport fountain pen and rollerball pen:
A note about using the Monteverde Mini Converter with the Kaweco Sport: Because the connector for the ink cartridge in the Kaweco pen is very short, some writers find that the converter wants to “pop off” of the connector or does not seem to attach very securely. This can be remedied by wrapping tape around the clear part of the converter. Wrap it with tape once and check to see if it fits the pen securely. If not, try wrapping it with tape a second time and it should stay put.
Since the plunger on the Monteverde Mini Converter is so easy to use, the Mini is a useful tool for using water to flush out the feed of some of your fountain pens or rollerball pens (assuming that standard universal cartridges fit in your pen).
