Bests & Worsts Reviews from Amazon

I don't do much watercolor media myself, but i do go into ink drawings. I got the idea from a picture on Google i found a while ago with one of these water brush's filled with black drawing ink. So i took a chance with this one, since reviews on this say that water flows nicely, so i just thought "why can't ink as well?". I bought this "Pentel Aquash Water Brush" and a "Zig Cartoonist Highly Opaque Pen Ink, Black" and tried it out myself. the conclusion was that it created one of the best black brush pen i could buy at this price. I've uploaded pictures of this creation.
