About this toy

One box. 167 pieces. 10 things to build.

Hand a kid a screwdriver and watch what happens. This building set comes with real nuts, bolts, plates and wheels sized for small hands, plus kid-friendly screwdrivers and wrenches. Follow the picture booklet to build a crane, a helicopter or a robot, take it apart, and build something new tomorrow.

10 models in one kit

  • Tower crane, crane truck, forklift and grabber car
  • Rocket car, racing car and UTV
  • Airplane and helicopter
  • A robot with moving arms

Builds one model at a time, so every rebuild feels like a brand-new toy.

Why families love it

  • Real tools, made for kids. Turning screws and tightening nuts is half the fun.
  • Step-by-step booklet. Clear picture instructions kids can follow on their own or with a parent.
  • Build together. A great screen-free project for a rainy afternoon, a classroom or family time.
  • Storage box included. All the pieces pack back into the box, so clean-up is quick.
  • Easy to wash. Bright plastic parts can be rinsed clean.
