Hair 'feathers'

My daughter told me our hair salon offers something like this. I have not seen them yet. But I am intrigued. Has anyone tried these ? I'd love to hear from you. Its interesting to me that you can curl / straighten them like your own hair. If they are real feathers, it doesn't seem like that is possible.

I have a hair appointment 3/24, I am going to be looking at these. My salon sells them for $30, I see them MUCH cheaper on line, but I want to see theirs vs. what is on line... I want to see how you get them in your hair. I have not seen ANYONE with these, and I am probably too old for them, but since I am immature and inappropriate anyway ( hahahhaa ) I think it will be fine.
