There are 11 fairy wing brushes in this set, 4 butterfly fairy wings, 5 fairy wing, 2 feather fairy or angel wings.
Each brush is a left wing. To get the right wing, simply duplicate the layer with the wing on it then transform it to where you need it, either by Distort or Flip Horizontal. Check out the free tutorials on my website to learn all you need to know about how to do digital fairy wings.
