Silicone Mold Cabochons Big Heart Jewelry Making Resin Polymer Clay Push Mold. I make all of my molds, pouring them by hand and using Vacuum Chamber Degassing to remove all air from the silicone. Our molds are flexible which make them easy to clean and release. Please wash before using. Flexible mold is easy to use with resin, polymer clay, metal clays, earth clays, urethane, wax and any casting or push material. All molds are handmade to order brand new, not used.
