Joseon Royal Wine Stopper This wine stopper was designed with the same reverence as crafting an item worthy of the Joseon royal court, reflecting dignity and splendor. When you open a bottle, do you worry about having to finish it all at once? This wine stopper allows you to reseal it effortlessly, making it ideal for those who enjoy a quiet drink alone or wish to sample several kinds of wine without waste. It can be used not only for wine bottles but also for whiskey, liquor, and oil bottles. Even those who do not drink can use it conveniently for beverages such as champagne or sparkling water. The stopper’s five-tier ridge and spiral structure ensures a secure seal for bottle openings between 16 and 20 mm in diameter. The rubber part does not need to be fully inserted for proper closure, as sealing strength may vary depending on the bottle.
