To use this Yoto story card pack, simply insert the card into your Yoto player. Then sit back, relax, and enjoy the amazing stories. There aren't any strict rules for listening, so your kids can listen to the stories in any order they like. As for storage, keep the cards in a dry and cool place to prevent any damage. If the cards get dirty, you can gently wipe them with a soft, dry cloth. Make sure your Yoto player is charged or connected to a power source before using the cards. And always handle the cards with clean hands to avoid smudging or scratching.
