They're markers. They do what they're supposed to do, mark. They don't write as nicely as Sharpies, but they get the job done in a multitude of pretty colors.
These flat-nib felt pens only appeal to calligraphers, but they are SO portable, to have in a shirt pocket to use on the fly, and, in several colors. But either these are not made any more, or Overstock has the sole supply. With a calligraphy pen instantly available, I find that if I write someone's name in 24 fonts on a 3x5 card, I remember their name, and they never forget ME.
