Nontoxic wooden marble run toy by Haba.

• The balls race down the starting track only to get stuck in the ball collector where they back up until the "stop & go lever" is released at which point all the balls race together towards the funnel.
• Once through the funnel, the balls continue down the track to knock over the dominoes. Balls measure 2" in diameter. Made of beech wood and ABS plastic.
• Contents include: 1 ball collector, 1 ball hopper, 1 curve, 2 straights, 1 swing ramp, 8 connecting elements, 5 columns, 2 starting ramps, 1 exit ramp, 2 connecting cuffs, 6 dominoes and 3 balls.
• Can be perfectly combined with all other Kullerbu ball track sets and accessories to create expansive layouts, stimulating creativity and imagination while encouraging creativity.
• The world of Kullerbu offers something for everyone ages 2-8. Younger children delight in sending balls down the track and learning cause and effect. Older children will learn about trouble-shooting and problem solving as they take part in the construction.
