The Adjustable Champagne-Wine Cap is an essential accessory for wine lovers. Made of high quality plastic, this cap is easy to handle and has a soft-touch finish. Its adjustable design allows it to fit a variety of bottle sizes, even those with a wide mouth. This stopper not only keeps the wine fresh for up to 2 weeks, but it also slows down the oxidation process, preserving the properties of the drink longer. In addition, it is perfect for champagne and other sparkling wines, as it helps to keep bubbles.
