Six molds in one set means I can pour a whole batch of coasters at once, and the silicone peeled away from the dried resin without any sticking. The octagon shape is my favorite for the geode texture, it gives each piece a nice organic edge.

The geode texture on these came out incredibly crisp on my first try, and the octagon shape is my favorite for a modern look. I've already poured three sets of coasters for gifts and the silicone released every single one without any sticking.

The clear silicone releases the cured epoxy like a dream—no wrestling or prying needed. I love having all three shapes in one set for mixing up my designs. These molds hold their shape perfectly after multiple uses, which is a huge plus for me.
