"TFIVE permanent paint marker pens are great. These pens can write on paper, cardboard, and even wood, but they also work on non-porous surfaces. I've used them on glass, pottery, and vinyl, and they've all turned out great."
"I recommend Frienda metallic marker pens. In my experience, and I have gone through almost a dozen of these markers, they always wrote smoothly. The ink dries fast as well."
