The boppi bamboo marble runs are eco-friendly and fun. Create and build multiple structures using the interchangeable and connectable parts to allow the marbles to travel from the top of the marble maze to the base via the spiral drop, rail tracks, and direction cylinders. Suitable for tabletop play due to the round exit rope that collects the marbles as they finish the journey. Made with bamboo fibre, wood, and 100% recycled plastic. Includes - 89 Pieces + 16 Coloured Marbles + Full Colour Inst
