I've constantly heard good things about Ohuhu markers, and I finally decided to jump on the bandwagon to see how they do. And, I have to say I enjoy them. Although the numbers can be confusing on some of the 6 and 9's, and the shade from number to number jumps a bit at times, I like how they feel, and once you get swatches down for all the colors, you can know what to expect. I included images of the swatches I did for my markers, so that you can see what they look like on my sketchbook paper (Canson Mix Media 98lb). There was some shadowing on the back of the paper, but no bleeding, even on the heavier colors. But that is for swatches, coloring may lead to bleeding, no guarantees either way though from me.
