If you find that you're wasting a lot of wine by leaving it open until it spoils, this handy invention could be for you.
'Wine condoms' are designed to save your unfinished bottles of wine, with the rubber device rolling over the rim of the bottle to preserve your booze and prevent any spills.
They also make it easier to transport bottles that have already been opened.
What's more, they even come in condom-style gold foil packets.
See how they work in the video above.
