Empoli glass bottle stopper MCM turquoise blue rectangular decanter topper

Empoli glass bottle stopper, a classic MCM midcentury modern design. Made in Italy. Teal / turquoise blue, rectangular shape, pattern looks like the letters L I, though it's just an abstract brutalist design. It once had a plastic stopper around the bottom, which would need to be replaced with something if you want a good seal. I do NOT have the bottle and it is NOT included with this sale - this sale is just for the bottle stopper - but I am including a photo of what this topper looked like on the original decanter. If you are lucky enough to have the bottle but are missing the stopper, this is a chance to remedy that! It's in great vintage condition, no chips that I can find.
