I was recently surprised by my son's beautiful artwork....red & purple crayon all over my white walls in the living room!  I was upset and worried that I wouldn't be able to get it off and I am currently renting a home.  To my surprise, the Mr. Clean Magic Eraser got ride of every single trace of color crayon that was on the wall.  I was pleasantly surprised and have been telling every one of my friends that they must get this product.  Any parent should always have one of these on hand, they are simply amazing!! :)
