Frog with ladybug craft mold will make a finished piece that will measure approximately 12 inches by 10 inches and is 1 1/4 inches thick. All of our molds can be used with concrete, cement, plaster, soap and resin. Comes with basic instructions for creating your pieces. Our molds are made of several different blends of polyethylene plastic which allows you to use the molds over and over. Our plastic is somewhat flexible so it allows for your finished pieces to be removed from the molds easily. This is a mold to pour into to make your own stones.
