The Mould King US Truck The Black Monster from the Creative Idea series offers a challenging building experience for fans of heavy commercial vehicles. Made from 1797 building blocks, it creates a detailed model of a classic American truck. The finished model impresses with functional details such as opening doors, a hood that opens, and distinctive chromed exhaust pipes. The blocks feature high stability and are compatible with building blocks from other well-known brands. A printed paper manual guides you step by step through the assembly of the large model.
