Zork - Cork & Closure in one
A revolutionary wine closure with the convenience of a screw cap
and the pop of a cork. Zork: Australian for cork.
The ZORK is a combination closure and pull-off capsule which fits
on many standard 750 ml wine bottles, including the 750 ml burgundy and Bordeaux bottles we sell.
Once opened, the closure essentially becomes a re-usable T-cork!
We will be stocking the ZORK in 6 colors:
Burgundy, Red, Black, Blue, and Gold. Yellow to follow in several weeks.
#336250 Black, #336251 Blue, #336252 Burgundy, #336253 Gold, #336256 Red, #336259 Yellow
Bags of 25: $ 11.25
Bags of 100: Add a ‘-1’: $ 44.00
