How to use: Just take the two trucks out of the package and start creating your own Monster Jam showdowns! You can race them, make them jump, and have a lot of fun. Notice: Keep these toys away from small children under 3 years old as there may be small parts that could be a choking hazard. Also, don't expose the trucks to sharp objects or strong impacts to avoid damage. Maintenance: You can use a soft cloth to clean the trucks if they get dirty. Store them in a dry place to prevent rusting. Have a great time playing with your Monster Jam trucks!
