Up for sale is a beautiful matching pair of vintage Mid-Century Modern amber art glass stoppers. These iconic flame-shaped, ribbed toppers are original Italian glass pieces, most famously paired with Empoli genie bottles and decanters from the 1960s. They are the perfect replacement if you have an empty bottle or want spares for a vintage glass collection! One has a mark on it, but it is not a crack in the glass. It looks like an imperfection when it was made see pictures.
