Filling: Omas' "Advanced Cartridge System" - there is an internal tray which holds two short international standard cartridges. (You'll need to load two cartridges in the tray in order to get the front one to puncture.) When the one you're using runs out, there's automatically one in reserve. No converters will fit this model. Some people have reported that they can use the long Waterman cartridges, with varying results.
