12 months & up. My First Toolbox contains components such as nuts, bolts, screws, connectors and gears as well as a screwdriver and a spanner. The various components can be attached to the toolbox or used as part of a construction project. Little ones can sort the components by color, shape, or by what tool is used to manipulate it. The different holes in the sides of the toolbox allow for it to also be used as a shape sorter. This set is great for developing manipulation skills, dexterity, and reasoning. It encourages cooperation and facilitates hand-eye coordination, developing fine motor skills and interpersonal skills.
