Kaweco Standard is a fountain pen converter to use normal sized pens with bottled ink. It fits well Kaweco DIA, Student, Special, Allrounder, and SUPRA (in long configuration). It will also fit many other fountain pens that use Standard International cartridges and converters.
This converter is too long for Kaweco Sport and Liliput compact pens. If you have a pen from the Kaweco Sport series, you need Kaweco Mini Converter — it was designed specifically for this model.
Please note that this converter will not fit Faber-Castell pens (save for WRITink series).
