Tecno Jumbo Toolbox has everything a child needs to build a world of trucks, excavators, cranes or anything else that comes to mind. Screws, bolts, wingnuts, wheels and perforated plates, made of resistant shatterproof plastic, can be assembled without special tools. All a child needs is a pair of hands and a lot of imagination. When playtime is over, everything fits back into the handy tool box. The box has a handle and a cover that can be used as a base for playing on. This building toy stimulates coordination as well as logic and creativity, helping children to understand basic principles of mechanics while enjoying themselves.
