"Nevers" Copper miniature clover set mystery

Here's another great mystery. Found these at a local flea market. Me being a clover collector I just had to have them. They came with a copper tray that is also marked "nevers". I cant find much information at all accept "nevers" was a French company. Does anyone on here have any clue as to what they may be? They're small. About 3 inches tall. Pure copper.
