Honestly haven't seen them before but searching on ebay, they do exist. I guess they're meant for wear on jacket collars. Maybe they're a foreign make.

 

Looks a lot thinner than normal, but the pin on the back and brownish appearance of the paint appears to be the French style.

Here is a regular French type.

Thanks. Theater made!

Typically, these are French made.

Yes, the do exist, both US and foreign-made. The were worn on collars and overseas caps. Not uncommon Insignia.
