I found the attached object this weekend at an old home site. It has a rounded end with, what looks like some type of structural ribs.. and a knurled flat end on the other. It appears to be hollow, but we could not unscrew the knurled end, so I am not sure if it actually opens. If it does open, I assume an old lipstick case?? It looks smaller than the ones I have googled... but I have no idea. Thanks
