I like to use the chalks on my vintage pages. You can use them to distress the edges of papers. I have even used them to change the color of a paper just a little bit by lightly brushing the chalk over the entire paper. The chalk stays put and doesnt rub off. The best thing about it though, is if you make a mistake, you can just erase it and start over. I rated it a four because the only down side, if there is one, is that you have to be careul not to drop the box because the chalks can fall out and break.
