Using these Bluey Mini Racers is super easy! Just grab a racer by its body, which is designed for little hands to hold. Then, give it a gentle push on a flat surface, and watch those free - rolling wheels go. You can race multiple racers against each other at home or take them out to play with friends. Since they're small, they're great for carrying in a backpack. As for maintenance, keep them away from water to prevent any damage to the wheels. If they get dirty, you can use a dry cloth to wipe them clean. Remember, the styles are randomly selected when we send them out, so if you have a specific one you want, tell us in your order. These toys are for kids 3 and up, so make sure younger kids don't play with them unsupervised to avoid any choking hazards.
