Some assembly is required. For shipping safety the bails are not yet attached to the bottles. To put closure on bottle make sure the wire bail is on one side and the swing cap on the other. Put one wire prong in one hole and slide the other prong along the glass until it clicks into the other hole. Voila!
The EZ cap bottle has a special closure, more commonly known as a “Grolsch” style closure, which is a wire bale which swings a ceramic style cap and rubber gasket upward and over the neck to seal the bottle. The most obvious advantage to this style of bottle is that it is easily resealable. These great bottles are smooth sided, making labeling very easy! They are thicker and stronger than regular bottles. One interesting point is that since the tops are reusable, they are more environmentally friendly. These traditionally styled bottles call attention to the craftsmanship put into the contents. Perfect for showcasing your special home brew beverages!
These EZ-Cap bottles hold 500ml or around 16.9 ounces. EZ-Caps bottles are about the same height but much wider than standard 12 ounce beer bottles as shown below. Some people recommend taking the gasket off and flipping it over between uses, which would at least allow you to inspect the gasket.
