Kaweco Refills AL Sport Squeeze Converter Fountain Pen - KWSQC by Kaweco Pens
Aerometric squeeze converter for Kaweco Sport Fountain pens. Simply attach to the Kaweco sport fountain pen front section like you would do with an ink cartridge. Then dip the nib into a bottle of fountain pen ink and squeeze the plastic bulb of the converter to create a vacuum of suction when released drawing ink up through the nib and into the bladder of the converter.
