Silicone mold for 4 Holographic Geode coasters. The coasters are 12.5 cm (5") wide and 8 mm (1/3") thick. These coasters are the same as our normal round Geode coasters, but then with a holographic color effect, which will transfer to the surface of your resin coasters.
There are also matching holographic molds for a coaster holder and a large tray, see one of the pictures (for illustratives purposes, this item is only for the coaster mold). We also combined the 3 molds in 2 different available sets, for special setprices.
