Works, but not for me.
I do not have the eyes for wings. I have very hooded eyes and while the little wedge shaped stamp works, the creases change the wing shape, which is not the products fault.  On the other hand, the other side has a great eyeliner pen that lasts all day and doesn’t smudge. So not a complete waste. I say try it if you have trouble drawing on your own wings.
