Vintage 60's German Monopol Spring Loaded Champagne Wine Bottle Stopper Keeps your bubbly bubbly for up to three days after opening. This is a vintage champagne keeper from before the Berlin wall fell. Made in West Germany in the 1960s. Reminiscent of something from a Aubrey Hepburn movie. Spring loaded and with a rubber seal. just clip onto your open bottle and place on the fridge. Would make a great gift for a wine lover or vintage alcohol enthusiast.
