Made of high-quality metal alloy material, it's smoothly polished, durable, and ensures a stable and long-lasting yo-yo experience. Features a fixed dynamic bearing, keeping the sphere spinning for an extended time and satisfying children's play needs. As a classic childhood pastime, it enhances hand-eye coordination, improves athletic ability and divergent thinking, making it a great educational toy.
