Fine point makes it easier to do details, and things that require pen-sized points. New pastel colors makes for a variety of colors besides just the usual bold ones. When you color something in with them, you can hardly see the streaks, lines, and scribbles from your coloring. My only comment is to make sure that you don't get the ink on anything other than your skin, and the paper, because the marker IS permanent! But besides that, I LOVE THESE MARKERS!
