Description: The vacuum wine stopper is used to store red wine. In the vacuum principle, the red wine is in a vacuum state to achieve the preservation effect. Use a vacuum stopper to plug the bottle mouth, and use the cork pump to pump out the air in the bottle until the pump is pulled up and then automatically bounces back to the original position to achieve the preservation effect. Press the stopper tightly to prevent air leakage. Before removing the stopper, gently shake the stopper to balance the pressure inside and outside the bottle, and pull out the stopper. If you want to clean, please rinse directly with warm water, do not use equipment such as dishwasher.
