Hey , I'm Guna go with not a cigaret holder and not a card holder.
I think its just A simple portable mirror, not too old probably.
I seen them used as a portable table lol.. for chopping stuff with a razor blade.
Hey Kevin, small world isn't it.
Probably run into ya at the garage sales.
Best of luck treasure hunting there is lots of different stuff to be found.

Funny cause that's the only use I've ever been able to come up with, and I might have used it too, but that's a bit too rich for my blood! Funny though when I search Cocaine Mirror on google I find this ad:
Amazon product ASIN B07VBCHHV2
The insides of this case and mine are exactly the same, just bare metal
IDK, maybe it is a compact mirror XD The metal reflects very well just as good as any "mirror glass"
