Hello FPN! I firmly believe that to enjoy your new pen, you have to have a good range of approved inks for coupling. There are certain inks that I believe "works" and "not-work" through a purely aesthetic judgement... With that said, new to my stable is a Sailor KOP - black ebonite. I am having a very difficult time finding an ink colour that goes well with this big black pen! I want to ask you...What ink(s) do you have in your black pen? (pictures with both the ink/pen combo will give you bonus brownies points!) Thanks everyone!
