These marbles are really easy to use. For the games, just follow the game rules that come with each set. You can play with friends or family, it's a great way to have fun. When collecting, you can display them in a nice place to show off your collection. As for maintenance, keep them away from sharp objects to avoid scratches. And when you're done playing or displaying, store them back in the net. It's important to note that although they're lead - free, they're small objects, so keep them out of reach of young children to prevent choking hazards.
