Hey, that was my auction! Don't worry, the pen is great. I was "thinning the herd" and had a really tough time deciding if I should keep this Copper SJ or another. The coloring on this one is beautiful! Please, if you have any issues with the pen, let me know.
As far as the nib goes, since it's a 9550, it's a firm extra fine, so hopefully you like fine nibs. If you don't know much about Esterbrook nibs, check out
this page. It tells you what all of those numbers mean on Esterbrook nibs.
Enjoy!
