Square Silicone Coaster Mold - RIM

Regular price $8.00

Looking for a simple square coaster? Then this mold is for you! Nicely sized and with a slight rim to keep the condensation from running all over your table. You know what I'm talking about...

Have enough coasters? Pair with our Bear mold and make an adorable trinket dish!

Measuring 4" x 4", these molds are

  • Flexible, soft and reusable
  • Made of non-toxic food-grade silicone; BPA free
  • 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.

    I especially like that they have rimmed sides to catch condensation from icy drinks!
