52 pieces behind 24 doors. 10 vehicles: a cement mixer, a wheeled excavator, a bulldozer, a dump truck and a wheel loader in yellow, plus a six-wheel utility truck, a big cab tractor, a small open tractor, a combine and a wagon in green. 41 accessories: 6 cones, 6 workers, 9 rocks, 4 yellow drums, 4 barrel stacks, 4 road barriers, 2 traffic lights and 6 signs. And one fold-out farm play mat.

Ages 3 and up. The vehicles are 5 to 7 cm, but the cones, rocks, drums and signs are small parts. WARNING: CHOKING HAZARD. Small parts. Not for children under 3 years. Keep the small pieces away from babies and pets, and check the set before you hand it over.

Each vehicle is 5 to 7 cm (about 2 to 2.75 in) long, small enough to hold in a 3-year-old's fist. They're little toys for little hands, not big trucks for the sandpit. Our photos show them next to real hands and mugs so you know what to expect.
