This bottle stein cap has a cap seal that, in most cases, will prevent your beer from spilling if you tip the bottle over. It is definitely a conversation starter. I have had many comments on my stein cap with people wanting to know how to get one. The price is reasonable and they make a great gift for friends. Only issue I had is the pivot pin came out after extended use. I crimped to end of the pin slightly reinserted it and have not any other issues.
Great Gift Idea
ConsThe pivot pin may come loose and fall out after extended use.
