Silicone mold is flexible and non-stick so pieces can easily be removed from the mold. Silicone mold is great for chocolate but can also be used with isomalt, soap, candles, and more. Mold has 30 cavities, letters A-Z and four black cavities. Heat safe up to 445°F. To use mold with chocolate: fill each cavity with melted candy coating or melted and tempered real chocolate. Tap molds on counter to release any air bubbles. Place mold in the freezer 10-15 minutes or until the chocolate is set. Turn mold over to release chocolate pieces.
