Irregular Square Coaster Mold - 4 PK

This irregular shaped coaster mold gives you a bit of unexpected whimsy for your next coaster project! Requested by a customer, we are delighted to add this fun and soon-to-be "go to" coaster to our collection. The organic shape is sure to be a crowd pleaser!

And they come in a 4 pack, because one mold just isn’t enough! 

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.
