This set is pretty cool. Not what I expected, but cool. They are essentially cut outs. All you have to do, is punch them out, then bend the wings up, and put the double sided sticker/tape on. After that you just have to find a place to stick them.
I am not quite sure that you can put these on the wall. They may tear off the wall paper or paint. I stuck mine onto surfaces that I don't have to worry about, like our television stand. I have to say that from far away they actually do look pretty real. The colors are marvelous. I think they are pretty sturdy for what they are made out of.
