Kaweco Classic Sport with double broad nib. Here’s an ink I had never used, but I found a leftover sample vial with just a little bit remaining. That’s a perfect situation for the Kaweco Classic Sport. I don’t need to go through contortions to fill a Sport from a small sample — I can syringe whatever ink is left into the pen body or a converter.
Here is Ama-iro with the Kaweco double broad nib.
The Kaweco Sport also lets one easily swap nibs. So here’s Ama-iro from an extra-fine nib, for Fountain Pen Geeks forum.
But I’m in it for the bling, frankly. So for me the eyedropper is key. Especially when the ink is a beautiful sky blue like Ama-iro.
