Well I have a few of these markers. All I know is that they are waterproof markers. Similiar to the SU markers and CTMH markers. They are a good bit cheaper than the copic markers to. Of which I own about 10 of the Copic Sketch ones. I actually like the ease of the Tombow markers. Their brush tip point are really easier to get in those tight places. I am on the search for watercolor paper. All home scrapbook companies carries it. As well as Gina K and Papertrey Ink. DECISIONS DECISIONS!!!
Any way here is the color chart for the Tombow Markers.
