This is a premade rainbow Grillz modeled on Pharrell Williams Grillz which he bought in 2013. He has since bought another Grillz in the six figures from Gabby Elan Jewelry, a Diamond District. This Grillz is a multicolor enamel with a silver and gold frame option. You can get just bottom or top or full set grillz. 18K PLATED GOLD GRILLZ FOR YOUR TEETH: Gold is Plated over human-safe brass so it will never tarnish easily. EASY TO USE: Just press down on each side of your teeth with our molding bar, then place our reshapable silicone bar into position and bite firmly until set. You can adjust or re-mold as needed by reheating with a hairdryer. SAFE, CUSTOMIZABLE: Our molding bars will fit the Grillz according to the shape of your mouth after adjusting the Grillz. Our reshapable silicone bars allow you to remold the bars. And also you can clean the silicon bars and keep them in the package for future use
