Kaweco Mini International Converter
If you're looking to use an inkwell for that fabulous Kaweco Sport, you'll need a mini converter to fit the smaller barrel.
Use this converter instead of a cartridge and you'll be able to use any fountain pen friendly ink from a bottle! This is opening up your Kaweco Sport to a whole new world of color!
Filling capacity: 0.47ml - *Nope... it's not a lot but it works to bring you ink options and that's what counts.
