These ultra cool Holographic rim coaster molds come in a two pack for each shape, with two different holographic designs.
The Square and Hex shapes are just over 4" wide and the Round shape is 3.3" in diameter.
Note: The holographic effect shows up best with a dark background. A flood coat will minimize the effect as it is created by tiny variances in the mold itself.
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.
