Mini Champagne optimizes the internal structure to make the cork fit more tightly on the bottle mouth, tightly lock the gas in the bottle, prevent the bubbles from slowly dissipating after the bottle is opened, and realize the efficient preservation of reunion. The bottle stopper adopts a unique cap shape design, which fits the chubby arc design of the sparkling wine bottle, with a more harmonious style, mini size, small and exquisite, and easier to store. The wine bottle stopper adopts a rotating design. It is only necessary to rotate the upper part of the wine stopper to unlock it, and then insert it into the bottle mouth to tighten it, and then turn the upper part of the champagne stopper back to its original position and lock it to achieve sealed preservation. The intimate finger position design makes it more comfortable to use. The champagne stopper has carefully added three small grooves that fit the fingertips on the upper part, making it easier for you to focus and use when rotating. The internal sealing parts of the wine stopper are made of food-grade silica gel, which is more comfortable to use.
