This is a really good imitation of the tools we adults use, and I'm sure your children will love playing with the many plastic tools you get with the work-case. The dark green Bosch drill is the perfect one, for it works by Means of two 1.5 Volts batteries! There's so in adjustable spanner - you move the thumbscrew and the movable jaw opens and closes, a claw hammer, two big nails, four red hexagon nuts and four black bolts, a handsaw, and two light brown plastic boards with four holes each and with grains to seem made of real wood! My nephew loves them all and plays a lot with them.
