This Review Title is Not chalk at all. More of a greasy stick ... and the content is: Not chalk at all.  More of a greasy stick of color.

Also, you need to wash a couple of times to get all of the color out..There are other information for this review, one is This reviewer did purchase it and the other is 0 people think this review is helpful.
