“Fantastic little device, means I can refill the pen multiple times, without adding to landfill. Works really well,not much ink so refilling more often but that's not a problem”
“Fits the Kaweco Sport but quite tiny and probably this pen should use a cartridge instead. Good service from this Aussie company and will shop here again.”
“The Kaweco sport is a great everyday carry but you need the piston converter to get the most out of your ink.
Forget cartridges buy this for every Sport you own.”
