At just over 4” in diameter, these molds are Flexible, soft and reusable Made of BPA free silicone Heat resistant: -40 to +446 degrees Fahrenheit, (-40 to +230 degrees Celsius) Non-stick for easy release Tips (always follow instructions for the resin you are using - these are meant as general guidelines): Always pour your resin into the hardener (pour hardener into the mixing container first, then resin). Stir resin with a plastic or silicone stirring stick to reduce air bubbles. Wood is not recommended as it can create air bubbles. Let resin sit a few minutes after stirring to reduce air bubbles. Don’t use a torch or heat gun as it could damage the molds and make it difficult to de-mould, causing them to tear - this is especially true near the edges. Wash mold as needed in warm soapy water.
