toga, Another new #fountainpen day, this time the Kaweco Sport Piston Filler. I really wish they kept the naming consistent and called this the Kaweco Piston Sport, but that's Kaweco for you. I was pleasantly surprised by how far up the piston actually sits. I haven't measured the capacity yet, but I'll do that when I next change the ink.
Side note: The "Kaweco Sport" name on the cap isn't filled in by default. I did that myself as I think it looks better this way.
