To use this Fiat 500 Adventure Construction Kit, start by taking out all the parts from the box. You'll find a metal body and doors that open. Put the parts together one by one - they're designed to fit easily. After assembling the car, it's time to get creative! Use the stickers provided to decorate your vehicle. You can add starting numbers, stripes, monster teeth, or camouflage motifs to make it unique. As for maintenance, keep the car away from sharp objects that could scratch the metal body. If it gets dirty, you can gently wipe it with a soft cloth. Remember, this kit is for kids aged 3 and up, so adult supervision might be needed during assembly and play to ensure safety.
