This 277-piece Huili Green Cow Supercar Building Block is designed specifically for boys over 6 years old. It uses eco-friendly ABS safe plastic, comes with rubber anti-slip tires, has thick and durable materials that resist drops without any odor, and smooth edges protect children’s hands. It includes a built-in Huili gear module; once assembled, simply pull it backward to activate the automatic sprint feature, restoring the real racing car sliding experience.
A replica of the classic supercar’s streamlined body, open cockpit, golden wheels, and detailed racing markings—complete with a fully functional mechanical structure that allows you to directly experience the gear transmission mechanism.
