This award-winning construction set is superb value and the ideal first building toy. With a box crammed full of gears (cogs), cranks, connectors and interconnecting base plates, there is almost no limit to the number of creations that can be built. And once everything has been put together the fun really begins! Children love to watch the colourful heavy-duty plastic gears spin and twirl together as they watch their creation come to life (and as a bonus they are learning about cause and effect while they're at it!). A fun and stimulating educational toy.
