great for beginners! My molds are made with flexible and high quality plastic, all made by me. For size, please check on the picture ,You can use my molds for resin, polymer clay, soap, chocolate, fondant, plaster. Some molds may not be deep enough for soap or plaster. For Polymer clay you may use a coating of baby powder for best results. You will received the plastic mold, not the molded piece. All my molds are made by order, please feel free to ask any question anytime.
