We make a variety of stainless steel construction sets for budding builders of all different skill levels. Our intricate parts are interchangeable with all Eitech sets, allowing both children and adults to be creative. Sets can have as few as 100 pieces or up to a 1,000 pieces. Build cranes, bridges, cars—even the Eiffel Tower. Whether used at school or at home, Eitech sets are the ultimate learning tool for aspiring engineers, teaching children valuable hands on motor skills, learning how to follow directions, and basic STEM skills.
