The tradition of metal construction sets dates back to the distant 18th century. Many generations of famous inventors, mechanics and engineers grew up on these construction sets. Thanks to this toy, boys (and girls) acquire their first skills in connecting parts with screws and nuts, develop their imagination and spatial skills. We recommend the TechnoK Excavator model for all little fans of special equipment. In addition to the excavator, a young engineer will be able to assemble other models from this large set of parts, as his imagination suggests.
