LARGE RESONITE MOLDS: To fill the entire resin mold, you may need about 1200 g of resin. If you plan to make a large pyramid, mold release is recommended and consider dividing your casting process into multiple steps. RESIN PYRAMID MOLDS: This large pyramid mold allows you to create pyramids smaller than 15cm, such as 4cm, 6cm, 10cm, etc. The mold includes external measurements for accurate sizing. DURABLE SILICONE MATERIAL: Our large resin molds are made from high-quality silicone material, which is flexible and easy to demold. Finished pieces have a clear, transparent appearance. NOTE: Carefully place the silicone mold insert into the plastic frame to ensure all sides are aligned. These silicone molds are intended for craft use only and are not food safe. How to clean: Clean the silicone molds with mild soap and water, then wipe with a soft cloth. How to store: Store the resin molds away from direct sunlight and dust. How to release: It is recommended to use "mold release". If unavailable, a small amount of soap mixed with water may be used as a release agent. Apply it to the mold and gently push the project out from the bottom. Ensure your resin piece is fully cured before demolding. A hard plastic stand is included; it provides stable support on flat surfaces to help create a perfectly square-based pyramid. The internal silicone mold fits securely inside the stand. Without the stand, the internal mold may tilt during resin pouring. The box stand includes engraved scale markings so you can create pyramids in your preferred size.
