I received them with only one crack, the crack had no broken glass just a micro crack/crack but they still had a lot of broken glass in them. Be sure to shake them all out and be careful not to cut yourself. I don't know where all the glasses came from. The plugs fit but are not very tight. I think 2 of them seal really well. need a higher density cork or maybe just rubber stoppers. Would buy again.
