Nissan and Nismo, though, have shown us something that we've truly never seen before. They've revealed some new car grilles. No, wait, they're not grilles, they're "Grillz," jewelry for your teeth that are inspired by famous Nissan cars. Apparently Nismo and Loud Mouth are also doing a giveaway for a custom set of Grillz, but not specifically a Nismo set. Based on the Nissan designs, Loud Mouth should be more than capable of creating a faithful recreation for your chompers, perfect for matching your own ride.
