I kind of like the blue stonewashed. It is the one I’d consider buying some day. How do you like yours?
I certainly like it very much. It's the color of blue denim, and very light. Comfortable to write when posted, and terribly easy to switch nibs with the screw-in nib unit (I got F, M and 1.1 nibs). I got them with clips, but as mentioned by someone else, somewhere else, the clip of the AL sports is not too tight, so it easily slips off, which is why I normally do not use the clip.
The clip of the D'like Alpha has a similar problem. But oddly, I found there is a cheap (3USD) clone of the D'like Alpha (itself a clone of the Sport), that comes with a clip that looks a lot like the classic-style clip of the Lilliput. Here, I must disgress, the classic-copper style clip of the Lilliput is very tight for the Lilliput. Well, this classic-style, steel-color, clip of the cheap clone is actually great, it is somewhat thicker than the ones that come with the Kaweco or the D'like, sturdier and fits a lot tighter. In one word, it is great for the Kaweco (or the D'like).
The only (well known) issue with the Kaweco is the small capacity converters. I got both, and much prefer the syringe-like one. I do not care that much about the capacity, it allows me to switch inks more frequently.
after having lost my black AL sport at the security check of Malaga airport (out of sight, out of mind ... the black of the pen perfectly blended with the black of the x-ray container), i finally gave in, and bought another one - this time, non-black.
showing here, because i didn't see a picture of the light blue version posted yet. the blue is really very light.
That is a very nice one. Looks really tempting. Let's hope I don't see it in real life at a B&M shop.
