Bottle stopper, 7 cm, vacuum, with date dial, plastic, Black, Bar

Bottle stopper, vacuum. Material: plastic, silicone. Size: 7x5 cm. Material: ABS plastic, silicone. The vacuum stopper is designed to remove air from a previously uncorked beverage bottle during its storage. A special stopper securely fixes the neck of the bottle, keeping the vacuum inside the bottle, thereby slowing down the process of oxidation. How to use: place the bottle on a flat surface; insert the vacuum stopper on the neck of the bottle; press the stopper rhythmically to remove air from the bottle (the less liquid in the closed bottle, the more pressure is required to remove air); turn the pointer on the top to the value that indicates the date when the bottle was sealed. It is recommended to wash by hand
