I am happily suprised by the white Faber-Castell Pitt Artist Pens in B, 1.5 and C. Last week I stumbled upon the set containing those three and a black pen in S. A couple of years ago I bought the big white pen with the rounded tip, but it was just too big to do highlights and I didn’t know there were other ones as well. I really do like the 1.5 for highlights. Not to bash the other two, because I like B and C very much . On my doodle below you can see all the white Faber-Castell pens and pencils on black paper. You can layer them to bring them out even more. I’d pick them over gel pens any day; they can be layered, they don’t scratch of, they go on top of coloured pencils, etc. (without giving up), they apply evenly, they are more reliable (my comparison: white uni ball signo gel pen).
