These marbles are the perfect size and weight for maximum track performance, and they come in red, yellow, blue, and green. Each marble has a diameter of 24.5 mm.
The modular and compatible marble runs are designed to stay put, so your kids can focus on the fun. They promote spatial intelligence and an understanding of fundamental physical concepts like acceleration and gravity. Whether with an instruction booklet or with free play, constructing a marble run stimulates working memory, and improves the capacity for analytical thought. And best of all, we’re building on an existing system to extend its life in the children's room.
Like all products from Hubelino, the Marble Set is manufactured in Germany under the highest quality standards.
