Here is my son, the window artist, hard at work. He is using Crayola window crayons and I am so excited about this product. My son has fine motor skill issues and getting him to spend a good amount of time colouring is tough. He spent about two hours drawing masterpieces on my windows the other day and just loved it. Every once in while I had to correct his grip, but most of the time he was practicing a good grip and not even knowing it.
(This product wipes off really easy too.)
