It was a Visconti Opera Master. Comes with a power reservoir filler that detached from the nib assembly within five days of purchase. Turned out the threads were completely mismatched, that pen should have never been sold. Now, granted Visconti has serious QC issues, but this was a limited edition and not only did Goulet fail to catch the issue during testing but they also refused to do anything about it except refer me to the manufacturer.

I ended up fixing the pen myself. It works well now, but after that experience, I am done with Goulet.
