Product Overview: Military Inertia Car 

While the primary movement is manual and battery-free (via the inertia motor), this specific version features a small internal battery compartment to power its electronic light and sound functions.

Key Features

• Inertia-Powered Movement: A simple forward push "charges" the friction motor, allowing the vehicle to zoom across the floor independently.

• Interactive Lights: Equipped with bright LED lights (typically in the headlights or roof siren area) that flash when the car is in motion or when a button is pressed.

• Realistic Sound Effects: Features built-in audio clips, such as engine revving, sirens, or tactical alerts, to immerse children in their military role-play.

• Openable Doors: Many versions of the 557 model feature doors that can be opened and closed, revealing a detailed interior and adding to the realism.

• Durable "Anti-Fall" Body: Constructed from thickened, non-toxic ABS plastic designed to survive the impact of high-speed "crashes" against furniture.
