How to use: Simply open the pack and start playing with the Hot Wheels cars right away! You can set up a race track at home or play with them on any flat surface. They're great for solo play or sharing with friends. Note: Since styles are randomly selected, don't be disappointed if you don't get the exact one you wanted. But you can always let us know your preference. Maintenance: Keep the cars clean by wiping them gently with a soft cloth. Avoid exposing them to extreme heat or rough handling to prevent damage. They're suitable for kids aged 3 and up, so adult supervision is recommended for younger children to ensure safety.
