This is a handmade Thick but flexible Poly-Plastic mold that is made to use with resin, but, can also be used with Clay, soap, Chocolates ect... This mold features a perfect size Football Helmet It measures approx. 2 1/2" wide to just a hair over 2" tall If pieces come out not shiny, simply coat with resin or resin spray. That is what I do with all of my pieces anyway. Do not put in the oven or near heat or flame.
