How to use: Simply take the two trucks out of the pack and start creating your own Monster Jam battles. You can race them, make them crash into each other, and have lots of fun. Notice: Keep these toys away from small children under 3 to avoid choking hazards. Also, don't throw the trucks hard as it may damage them. Maintenance advice: Wipe the trucks with a soft cloth regularly to keep them clean. Store them in a dry place to prevent rusting.
