Using this Hape Magic Cookie Baking Oven is super easy. First, take out the included tray and the 6 cookies from the set. Place the cookies on the tray and put it inside the oven. Enjoy the light and sound functions that make the baking experience feel real. When you hear the 'Ding!' sound of the oven timer, your cookies are 'done'! For role - play, your child can pretend to serve these cookies to their family and friends, which helps build language and social skills. Remember, this toy is for kids aged 3 and up. To keep it in good condition, use a soft, dry cloth to clean it. Don't expose it to water or sharp objects. Have fun baking!
