I prefer XF nibs, but thought I’d try this. It’s smooth, flows well, still a fine line like I prefer, with a nice line variation once I figured it out. It’s my first stub, and I’m very happy with it. It ads a touch of class to my writing, and it will be my letter/note writing nib. It’s a finer line than the Esterbrook example poster, but I enjoy what I have with it.
