The Kugelix-Duo ball track from nic convinces by its design and functionality. It features a natural and colourful look thanks to the combination of natural wood and the colourful tracks and balls. The parts can be connected to each other with plastic tongue dowels and create different itineraries. The balls make use of a billiard effect: Three balls are placed on the blue part of the track. The forth ball rolls from the top, kicking the first of the three balls – an effect, which makes kids curious to see more.
