Staedtler Triplus Fineliner Marker Pen - 0.3 mm - Violet Purple

I love these pens. I'm a teacher, and I use them to grade essays. The wide array of colors makes it very easy to color code my rubrics. I have the 10 pen set, and my only complaint is the colors chosen for this set. I'd prefer more bright colors instead of the brown, black, and yellow. For my purposes, the yellow is my only real problem (students can't see it very well, and it doesn't show up when photocopied). I will eventually replace it with a different color.
