Airplane propers from car air freshener?

[CB2001]

I was in Advance Auto Parts today picking up some parts with my dad for my car. I was standing next to him, waiting at the counter when I noticed a small wireframe cage with a bunch of airfreshers for cars on display. And to my surprise, one of them looked the most useful for anyone needed parts or scratchbuilding a model airplane. They are called Wildcat Air Fresheners. They clip onto the vent for your air conditioner and I thought it'd be a good thing to share for those who need airplane propellers.
