The Sharpie Permanent Marker is a classic, but does not give a classic performance in my Moleskine Reporter notebook. Not that I expected it to, but I wanted to try out the Ultra Fine tip anyway. It bleeds through the page really quickly, causing me to write at light speed. The following page in my notebook became unusable (in my anal-retentive mind) after this pen test. I think I'll stick to marking cd's and dvd's with this one.
