To use this game, first, take out the sample cards that show funny faces. Then, get the cardboard shapes and start sliding and overlapping them under the mirror to copy the faces on the cards. It's all about having fun and being creative. As for the age, this game is designed for kids 5 years old and up, so make sure younger kids don't play with small parts to avoid choking. When it comes to maintenance, keep the cardboard shapes and cards in a dry place. If they get dirty, you can gently wipe them with a soft, dry cloth. Enjoy playing with this magical game!
