I won an auction for a Sailor Special Gift Professional Gear with a medium 2 tone 21k nib. After I won it I didn't realize that there was another variety of nib for this pen, the N-T nib (abbreviated in order to avoid misspellings), which has in turn piqued my interest. My experience with pens is not that great and I don't have any experience with this brand or nib but thankfully many of you have some experience with both of these nibs and am curious to hear your opinions on both.
