Erector sets are the next step up for builders who have grown tired of the limitations of plastic building systems. Erector structural materials are made from metal so so the parts are both stronger and less bulky than common plastic building materials. Because components are held together with screws and nuts, you have almost total flexibility when aligning parts. Erector parts are nicely made and finished.
Erector sets give kids experience with more realistic construction materials and fasteners. They get a chance to explore more abstract 3D shapes because because connections aren't limited to a fixed grid pattern. They also work on refining their fine motor skills by assembling models with small screws and nuts using simple hand tools.
