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 has everything a child needs to build a world of robots, animals or anything else that comes to mind. Thanks to the perforated base, constructions can be made horizontally or vertically. Tecno Jumbo Starter Set stimulates coordination as well as logic and creativity, helping children to understand basic principles of mechanics while enjoying themselves.
