Bag of (30) blue colored Zork's. The Zork is a combination closure and pull-off capsule which fits on many standard 750 ml wine bottles. Once opened, the zork becomes a reusable T-cork. It may be put in by hand (a quick soak in warm water makes this easier) or with a wide head bench beer crown capper.
To open the bottle, tear off the sporal strip and remove the T-cork closure. Closure may be re-inseted repeatedly as you consume the bottle.
