Create your own resin agate geode coaster set with this silicone mold consisting of 4 individual wedge shapes.
7 in stock (can be backordered)
Each agate triangle wedge is approx. 21cm and 1cm deep. The individual coaster molds create a full circle and each one is large enough for a cup or glass to rest upon.
Clean with warm soapy water and keep dry and protected to ensure longevity. Do not use heat gun or torch directly over the silicon as this will shorten the life of your mold and may cause the resin to stick to the mold.
