This is a HABA Kugelbahn (marble run). It was used by a child, so there are scratches, stains, and signs of wear and tear from use. It has been stored at home for a long time. This is a brand that embodies the spirit of German craftsmanship. They continue to focus on quality, the best materials, and safety, allowing for long-lasting enjoyment, and they offer educational toys full of ideas to the world. You play by matching the height of the base parts and connecting slopes and blocks with holes to create a path for the marbles to roll down. This set includes the basic slopes and perforated parts, as well as zigzag slopes and a bell, so you have everything you need to play Kugelbahn. There are many optional parts for the Kugelbahn, such as fun slopes and blocks with holes. Please add to the set gradually according to the child's age and skill level.
