This was a wonderful project I worked on with my grand-nephew who is currently 3 1/2 years old. He loves planes!!! He was able to color the stickers and put them on the planes as he wished . . . it was a lot of fun. The only complaint I have is the stickum on the stickers was not adequate for them to stick well. Also, some of the stickers were hard to peel off without peeling the entire layers off but other than that it was a blast designing all the different planes with the nice variety of stickers. They also flew pretty good as well.
