Each mystery box contains 1 toy with 8 different construction site vehicles to collect, including a road roller, wheel loader, dump truck toy, cement truck, wrecking ball crane, mobile crane, bulldozer and a toy excavator. These models give kids a great introduction to STEM building toys and engineering as each one includes a moving function powered by LEGO Technic pieces.
