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 double layed just over 2" wide x 2" tall Shamrock-It has a top layer that you make one color and a back layer that you can do another! 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.
