This kit allows children to enjoy building and playing with "screws" and "tools," which they love. The screws are close to real size, and by understanding the functions of each tool and choosing the right tool for the screw, children can play at being a carpenter more realistically. They can also learn the roles of "washers" and "nuts," and how to use tools often used in daily life, such as how to secure a "nut" with a "wrench" and then use a screwdriver. There may be parts that are not a Phillips head screwdriver. The photos show everything included. There is no Phillips head screwdriver, but there is a flathead screwdriver, so you can still open and close screws.
