I have and use the chalk wheels and the bohin pencil I use both a lot. I have white, blue, pink and green fine (chalk sticks) for the pencil and the roller wheels I have in white & blue- I use them all and have never had a problem removing the chalk. just don't iron over it (heat set the color) and I do always do a little *test* before doing a lot of marking to make sure it's going to come out.
