Pelikan Converter turns a cartridge pen into a fountain pen with piston mechanism and is for the filling of fountain pens from the ink bottle. The converter is installed into the fountain pen the same way as a cartridge. The pen is then dipped into a bottle of ink until the nib and part of the grip section is submerged in the ink. Subsequent the knob of the converter is turned until the ink is absorbed. The converter can be used for most Pelikan cartridge fountain pens.
