I'll find the link for you, but it's one site where they send you the kit for the mold, you do it your self, send the mold back and they send the grill to you after you design it online. If I'm not mistaken paul Wall does it too. I seen him talking bout the kit as well when he was doing Lil John's teeth. But buying grills isn't like buying clothes. If they dont fit right they can irratate your gums and teeth.
