Our standard converter in pearl black with chrome elements fits all our long fountain pens. Instead of two ink cartridges, the converter is inserted into the barrel of the fountain pen.
This makes it easy to refill ink from the ink bottle. Refilling multiple times in a row increases the fill level.
A major advantage of converters is the sustainability aspect:
Unlike conventional ink cartridges, which usually end up in the trash after the ink has been used up, it can be reused and refilled again and again.
It pairs particularly well with our Kaweco Pearl Black ink.
