On opening the package, you can't help but notice that these pens are cheap. I gave them a try, and it was better than expected. The set comes with 2 brush pens, a 0.8, and 0.6 to 0.1.
I don't general use brush pens and they felt odd to me. Actually very bad. The nib or whatever was very soft. The 0.8 to 0.5 felt pretty good. The 0.4 felt like the nib was bent, but all visual inspections showed it to be straight. The smaller pens felt really good. I could see using these a lot.
I returned to the brush pens and felt that maybe with a little practice, they would be ok.
So how do they rank? I'd say a solid 3 of five stars. If they last a long time, I could see bumping them up one star.
