Wine has been a beloved beverage for centuries. And back in olden times, the philosophy was, drink the whole bottle, because there was no way to preserve the rest of it. But alas, modern history is upon us, and we no longer have to let our wine go sour if we don’t finish it all. Rabbit Wine and Beverage Stoppers are here to help.

These cute and colorful little doodads are designed to fit right into the neck of all bottle types to form an airtight seal. Plug them in and set your wine in the fridge. They’re easily insertable and removable, and are even dishwasher safe. They’re made of strong rubber and stainless steel, so you don’t have to worry about leakage.

A set of four comes just under $7. That’s saving you money, and wine.
