[Product Information]

• Sometimes the simplest ideas are the best ones
• Such is the case for the revolutionary growler collar
• To the untrained eye it appears to be nothing more than a piece of round， white plastic adorned with the world-famous Keg Works logo
• But in reality， this piece of plastic represents a seismic leap forward in the science of growler cleaning
• Wash and rinse your growler thoroughly， then screw it into the threaded hole of the collar， letting gravity do its thing
