A model figure is a scale model representing a human, monster or other creature. Human figures may be either a generic figure of a type (such as "World War II Luftwaffe pilot"), a historical personage (such as "King Henry VIII"), or a fictional character (such as "Conan"). Model figures are sold both as kits for enthusiast to construct and paint and as pre-built, pre-painted collectable figurines. Model kits may be made in plastic (usually polystyrene), polyurethane resin, or metal (including white metal); collectables are usually made of plastic, porcelain, or (rarely) bronze.
