"My daughter is 7 and she has built a couple Friends series kits before. This jet is bigger than we thought and was challenging of for her to build. The length meant keeping track of dots all the way down the airplane body. She missed the count by 1 dot and had to start over the next day. The jet is very detailed and makes playing fun. The door opens sideways like a real airline door and there is a small frog with food items and a moving coffee pot. The roof pulls off easily for playing with the interior without pulling itself apart. Other than the color it would be a good set for boys as well."
