Did you see the brass grillz other sells have been selling? Well guess what...those grillz are maybe good for a Halloween party but NOT for everyday use! Brass turns colors and goes green in few hours...complete waste of money! Our grillz are made out of SOLID 925 silver! NOT PLATED Stamped 925 Will never turn color...Silver is a precious metal Silver & gold has been used in dental work for hundreds of years and lasts a lifetime! Top weighs 6g & bottom weighs 4g Grillz come with silicone/wax mold and case. We include extra silicone mold just in case you mess the first one up All you have to do is use warm water to melt the mold and then insert for a custom fit One size fits all!
