I think what you're looking for are pigma pens. I bought a set online a couple of years ago to use up here at our summer cabin. I have more at the winter place but they are different sizes. I like the .05 size because it is thick enough to do a nice label. The skinny pens .005 are really too thin and I have to go over my lettering several times to get a nice label.
You can usually find these at quilt shops, too. I don't know if Joann's carries them. I don't go there often and haven't looked for them.
