The CAT 4-In-1 Screw Truck Construction Toy Set by Theo Klein transforms from a truck to a digger, offering multiple configurations for construction-themed play. This 23-piece set includes a toy screwdriver that lets kids assemble and disassemble the vehicles, switching between a truck with wide tires and a low trailer, and a functional digger with shovel and spoon attachments. The detachable toolbox doubles as a tipping trough for pretend hauling and dumping on imaginary job sites. Designed for children aged three and up, the set combines hands-on building with imaginative construction scenarios.
