- Threaded type for Conway Stewart, Caran d'Ache and other pens that require a threaded converter. This converter is exactly the same as the type used by Conway Stewart (except it does not have gold-plating on the metal parts).
- Clear type that will fit most pens that do not take a proprietary cartridge or converter (except small cartridge-only pens). 69.5mm long, max diameter 7.4mm.
- Green type - same as clear.
- Mini slide converter for small pens. 61mm long, max diameter 6.8mm (note: this will not fit a Yard-O-Led Pocket Viceroy nor Sheaffer pens that took the Slim cartridge).
