Our pearl black standard converter with gold-plated elements fits for 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 fill up ink from an ink bottle. Multiple filling in succession increases the filling quantity.
A major advantage of converters is above all the sustainability aspect:
Unlike conventional ink cartridges, which end up in the trash after the ink has been used, it can be permanently reused and refilled again and again.
It goes especially well with our Kaweco ink in pearl black.
