There are two types of moulds available here. The newest Halloween moulds are the monster head moulds that include the Vampire/Pirate Skeleton mould and the Werewolf/Frankenstein monster mould. These have TWO different heads in each mould and the backs of the heads are also detailed. They are flat decorations with bases. You should be able to cast about 3 heads from one bar of metal. The average measurement is about 35mm in length (base) and height varies slightly at about 40mm.
The other mould type are the single moulds that allow you to cast Pumpkins, Witches, Black Cats and Ghosts to decorate your home or give them to friends as holiday gifts. One figure per mould. These are flat figures with details on both sides.
All these moulds are seasonally available and returns at the start of August. They stop being available in November.
