Made to fit the iconic CorkPops wine openers, these CorkPops refill canisters come in a pack of two so you can enjoy your CorkPops opener again and again - each canister will open up to 50 bottles! The inert gas used is not only odorless, colorless and tasteless, but also completely safe to use and will not alter the bouquet of the wine in any way, allowing you to enjoy glass after glass.
