I know this is an old post but I coulnt help but say I found one today and am happy you posted because I can’t find any others like this online without the ridges. I believe it was a perfume company but our bottles were used for a sort of talcum powder. Here’s what it looks like with the cap intact.What is this? The copper top was intact until I tried to remove it. It wasn't screwed onto the top, it was pressure fit, push on. It only says "BOUR JOIS" on the bottom.
