These markers are a ton of fun. They work like most others and are a liquid base so though they say chalk, be sure not to use them on anything porous. They work great on windows, plastics or metal. The included labels are a perfect example of a good medium. I would highly recommend these for anyone looking to branch out on this new popular art style.

Also they smear easily being liquid based on non porous surfaces. Get HERE ON AMAZON
