Fred and Friends CORKY seals your opened wine bottle as the ultimate fun wine preserver. Looking to keep the zest in your zin, the mmmm in your merlot? Put a cork in it! Even better, insert Corky and give it a few presses to evacuate the air trapped inside the bottle. Voila! Corky is made from durable, food-safe plastic that keeps your wine fresh as can be, even though you haven’t finished it.
