This kit lets children enjoy building and playing with their favorite "screws" and "tools." The screws are close to real-life size, allowing children to understand the function of each tool and choose the right one for the screw, enabling them to play at being a carpenter more realistically. A major appeal is that you can build both flat and three-dimensional structures by actually using the tools! It includes tires for making a car. L-shaped and U-shaped parts needed for building three-dimensional structures are also included. Some materials may be missing. Everything shown in the photos is included.
