I just love Sharpie ultra fine point pens. I have use the black one for a long time. It does not bleed through my paper and is so easy to use. Now they have come out with all these colors. I got this set of 24 at Walmart for 16.95. That is about 70 cents a pen. I think they are very comparable to the Micron pens as far as color and being permanent. Great for doing doodles and such.
My tip of the day so have a good one.
