I think these paint pens work fine. Though I've only ever tried one brand before. Just be careful and follow the directions and you shouldn't have a problem. Once you get them to work just pump down on them lightly the paint can come out pretty fast. If that happens I try to run the pen through the paint and even it out. It's nice that the box comes with free stencils in it too. I think the colors are nice. I don't know if they work on rock that well. I haven't tried enough to be able to tell that but they work fine on wood as you can see in the picture.I changed my review from 4 stars to a 3 because these pens run too much and can be pretty messy.
