Kaweco Foldable Mini Piston Cartridge Converter

Good

The converter is small, but I think we all know that. It’s great to have just in case you don’t have a cartridge to refill.

I like the device but it took many up and down to get it to draw up the ink

works like it should. I am enjoying this new hobby. Can't say enough good things about the folks at Goulet pens
