Silicone mold for a set of 4 irregular shaped Geode coasters. The coasters are about 12.5 cm (5") wide and 10 mm (2/5") thick. There is also a mold for a matching coaster holder, see one of the pictures (for illustratives purposes, this item is only for the coaster mold).
Both molds are also as a set available and there are also Druzy inlay molds for the Geode coasters.
