What’s inside the kit – 4 bases with wheels, 2 trailers with 2 wheels, parts to build a concrete mixer, bulldozer, tractor, garbage truck. There are cabins for cars and trucks. There are flashing lights, there are front attachments with headlights, which children insist on calling eyes. The photo shows all the parts of this set. The magnets hold the parts well, but when you move the car with a trailer, it’s better to support the trailer with your hand.
