The four giant chalks are just the same with the usual chalk but what is cool about this is that when you use a special glasses provided and included in the package you'll be able to make those drawn chalks pop out of the ground. I think this is great for kids and they will sure love it. I just hope that if I bought one of this Maki will just write on one specific place. We all know that kids are explorers so who knows what will happen then. We'll just cross the bridge when we get there. For now try one of this for you kids.
