Kaweco Mini Converter
The Mini piston converter is designed to fit the smaller pens in the Kaweco lineup, and also a few by other pen manufacturers. It fits all pens in the Sport series.
Note: This converter is not compatible with the Liliput fountain pen, which is smaller than the Sport. Holds approximately 0.5ml of ink.
Worked great with my Kaweco Sport pen. The price and quality was spot on. Thanks.
