Here, big and small constructors can build a super marble track. With metal rods and flexible plastic rods, a rapid descent is built up. The balls are transported back up with a battery-operated elevator. Now the ball starts again in a new round with looping, hairpin bends and spiral tunnel: A great lust factor! Material: plastic and metal Package dimensions: 50 x 18 x 24 cm Track dimensions: 6.5 meters Battery-operated track Batteries are not included!!
