I used both a pen and paint for these ("Porcelaine" brand) and the consistency of each took some getting used to. Now that I've got the hang of it though, I'm feeling hooked. It's a good thing I have a whole pile of plates to go through. The paint is dishwasher resistant, but I imagine these more as little depositories for trinkets or keys than for eating off of. I'm sure I'll end up giving most of them away -- because really, there's only so many trinket plates my husband will tolerate.
