A smart and stylish addition to any in-home bar, this sleek crown sealer eliminates waste by preserving the flavor and finish of previously opened bottles of champagne or sparkling wine. The unit features an air-tight food-safe rubber seal, which secures around standard bottle crowns to lock carbonation inside and preserve contents for days--no more flat, tasteless pours when serving from partially full bottles. To use, simply screw the device onto the top of an opened bottle, and then flip down its switch-style valve to lock in the pressure and maintain all that delicious fizz. The sealer's high-quality metal construction ensures reliable use from one bottle to the next, while its airtight seal allows for storing bottles on their side without leaking. With its sleek, contemporary finish, the champagne crown sealer measures approximately 1-1/2 by 3 by 3 inches and carries a 10-year limited warranty.
