I have found no better marker than a Copic. I am totally addicted and want every single color! I use my cool grays the most of any gray that I have. They are very versatile... great for coloring and shadowing. Also great for shading something to keep it looking white. Love it!
I ordered all Copic Sketch Markers, and got 7 Copic Markers instead of the Sketch Markers. That was disappointing.
