This is a 30 pack of black Zork wine closures
Zork is a combination closure and pull-off capsule that fits on standard 750 ml wine bottles. Once opened, the closure becomes a re-usable tasting cork.
Zork closures can be put on by hand with a quick soak in warm water, and creates a leak-free seal with both the internal cork and its tight grip on the outside. To open, tear off the spiral strip, and remove the tasting cork. The tasting cork may be reused as the wine is consumed.
Zork Wine Closures provide a better seal than natural cork products, and a professional finish without the need for either a corker or a corkscrew.
