I just got a Fons and Porter white fineline ceramic pencil. I am so disappointed! It barely makes a mark at all, and to get anything to show, even faintly, I have to go over and over and over the same area. Did I just get a lemon? Do I need to return it for a "fresher" one? If all of these markers are this way...what is out there that makes a fine line and actually works? Bummed! It wasn't inexpensive. SIGH....
