Bornelund Quadrilla Twist & Rail Set Around 4 Years Old QDE6009AB05

[Combinations are infinite] This is a course set for rolling balls made by combining blocks and rails. Quadrilla, which hides physical theories such as gravity and friction, is a charming slope toy that not only children but also adults will fall in love with.

[Roll a ball that you think is natural] Quadria is thought of as a simple repetitive game, but you can sensitively learn physical theories such as structure, acceleration, and friction by repeating trial and error, full of laws that you can focus on during play.
