The Quercetti Tecno Jumbo Toolbox Construction Set provides everything a young builder needs to create a world of trucks, excavators, cranes, or any other imaginative vehicle. This 86-piece set includes a variety of screws, bolts, wingnuts, wheels, and perforated plates, all made from durable, shatterproof plastic. Children can assemble these components using just their hands, encouraging creativity and an understanding of basic mechanical principles. When playtime is finished, all pieces store neatly back into the handy toolbox, which features a handle and a lid that doubles as a building base. This construction toy is designed to stimulate coordination, logical thinking, and problem-solving skills.
