Clay Jewelry Line Clay Jewelry Mold Round Glass M 3D Silicone Mold I opened it once to read the instructions, but the silicone mold is unused. Due to product specifications, the mold has oil applied to it. The included instructions state that this type of mold allows oil to gradually seep from the silicone to improve mold release. The instructions also state that it can be wiped off and used, so please check the instructions after purchase.
