Bolts, wing nuts, wheels, and perforated plates made of durable plastic can be easily assembled without any additional tools. All a child needs are a few hands and plenty of imagination to dive into this amazing world of robots, animals, and many other things they can envision. Thanks to the perforated base, structures can be built horizontally or vertically. The Tecno Jumbo Starter Set promotes coordination, logic, and creativity, helping children understand the basic principles of mechanics while having fun.
