Using this SmartMax My First Dinosaur Building Set is super easy. First, take out the pieces from the set. You can start building the dinosaurs by clicking the soft animal pieces onto the bars. Let your kids' imagination guide them to create different dinosaur shapes and combinations. There's a T. rex in the set, so when your kids are playing, they can pretend it's coming to attack the other dinosaurs. It's really fun! As for the age range, this set is for kids aged 1 - 5 years. For younger kids, make sure to supervise them to avoid choking hazards as the pieces are small. When it comes to maintenance, you can use a soft, damp cloth to wipe the pieces clean if they get dirty. Don't put them in water for a long - time as it may damage the magnetic parts. Also, keep the set in a dry place when not in use. This set is compatible with other SmartMax sets, so your kids can combine them for even more creative play.
