15001 Black Flex

I've been using it daily for two weeks and the piston filler holds a surprisingly generous amount of ink, which I didn't expect for such a slim pen. The flex nib takes a bit of practice, but once you get the pressure right, it's a joy for dramatic letter strokes.

The flex nib puts down gorgeous line variation without any pressure, and the ebonite feed keeps up even when I’m scribbling fast. It’s a wet writer, messy in a fun way, and the black body feels solid in my hand. Perfect for those long letter-writing sessions.

I picked this up mainly for the flex nib, and it doesn’t disappoint—the feed keeps up nicely even when I’m pushing the tines for dramatic line variation. The pen has a nice heft to it, and the black flex design looks sharper in person than the photos.
