This seashell candy mold is halves of a clam shell. You can make these for favors or even to decorate a cake with. These shells measure 2-3/4" and are 3/4" deep. There are 6 cavities on this mold and you will get approximately 12 shells per pound of chocolate. These would look cute to make a 3-D open shell with a pearl inside for a Little Mermaid cake.
