How to use: Just take the two trucks out of the pack and start creating your own Monster Jam battles. Push them around on a flat surface or create obstacle courses. You can also have races between the trucks. Attention: Keep these toys away from small children under 3 as they may pose a choking hazard. Avoid throwing the trucks forcefully as it could damage the details. Maintenance: Wipe the trucks with a soft, dry cloth if they get dirty. Store them in a dry place to prevent rusting. With proper care, these trucks will provide hours of fun for your kids.
