4 Brick design concrete stepping stone mold. This brick mold can create some really unique patterns for patios and walkways. The finished stone will measure approximately 8 inches and 16 inches and 1 1/2 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.
