These blue EZ Cap Swing Top bottles combine the convenience of a swing top, hybridized with the storage capabilities of a standard crown cap.  These swing tops are designed to be primarily sealed with a crown cap closure for long term storage.  Once you crack your brew for consumption however, you have the swing top in place to close it back up if need be!  Whether you're too distracted with other fine brews to taste, or just need to wait your turn at the beer pong table, this is a perfect system for you.
