describe: The internal seal of the wine stopper is made of food contact grade silicone material, which is safer. The shell is made of durable ABS material, which is not easy to wear and easy to clean. The unique "little hat" design is suitable for the bold arc design of the sparkling wine bottle, and the style is more harmonious. Small size, more convenient storage. The rotating design is more efficient and easier to use. Rotate the top of the cork to unlock it, then plug it tightly into the mouth of the bottle and put the champagne cork into it. The top is locked back to its original position to preserve the seal. Suitable for standard wine, beer, champagne and soda bottles, including some larger styles.
