KawecoMini Converter Sport 2 Pack, Black/Clear, Writing Instrument

Great quality, tiny amounts of ink though, had to be recharged often.

5 stars for the product itself. However it does not fit the Liliput unless you only fill it 25% of the way.It does fit the Sport.

At this moment I don't remember if it's specified in the description but, I could not use them in the kaweco sport, but they work for the kaweco collection pens.As for the usage, so far they are easy to use; refilling them and placing them in the pen is very simple.

I just ordered my tenth Kaweco -- yes, I'm a little bit addicted to those happy colors, plus they are great fountain pens for the price. Occasionally I've gotten a nib I don't love, but a little sanding and it's good to go. These pens last and last. I've had some of mine for years -- no cracking, no problems. They are faithful writing companions.Kaweco pens generally come with cartridges, some of which are beautiful (Summer Purple is my favorite) but I also collect inks, and that means I always get a converter when I acquire a new Kaweco. I've had mixed luck with the converters. Sometimes they fit perfectly, other times they won't play nice with any of my Kawecos. The dud rate is about 10%, but given the price, I'm okay with that.These converters also take a little practice to use because they are tiny, but if someone as uncoordinated/clumsy as I am can manage it, so can you.

Some folks gripe because these converters hold around half the ink of cartridges. If you like using a variety of inks in your Sports, though, these converters are absolutely perfect. They hold just enough ink to carry you through the "okay, time to shake things up" twitchiness that ink collectors inevitably get. And if you're not done with the current color ink? It's a converter so it's easy to add more ink. I don't completely fill large converters in my other pens either simply because I value the flexibility partial fills give me (or in the case of my Kaweco Sports, complete fills of my converters). I love these little guys.

I use it with my Kaweco Frosted Blueberry (broad nib) and Noodler's Polar Blue Bulletproof ink. Took my Kaweco Sport from great to outta this world.

the converters are OK but the plunger is really really tight and this converter is so short even with the feed still attached that it's not the easiest to refill from anything but a new full ink bottle.. even then you'll probably get ink on your fingers. Of course you can shoot em up with a syringe, but you could do that with an empty ink cartridge too, couldn't you. would be cool to have a longer design that fills the pen body just to make it easier to handle.I think I'll try the trick with plastic kaweco body pens where you just fill the body of the pen (no cart/no converter) with a syringe and then seal the threads with silicone grease.

I've had one in my Kaweco sport a few months now and I've had no problems with it. Stays in place even on a pen that rolls around the bottom of my purse and it's easy to fill.
