I am hooked on Sharpie pens for mark making. But every time I think that I own every single black permanent marker made, I discover yet another gem from this company. My newest art "toy" is a big fat chunky oil based black paint pen marker with permanent ink. Favorites among graffiti artists this product creates a shiny thick line which appears to cover over almost all over media. You get started by shaking the paint pen and then once you remove the cover, you are good to go and can make gorgeous black marks to your heart's content. As you can see, I have really "broken in my Sharpie paint pen.
