These caps are always of a good quality. I never have a product failure, just capping issues usually associated with getting in a hurry. Will buy again.

They work
I bottled some Imperial Stout and aged for 8 months. Not any spoiled bottles even after a year. I use these all the time. Everyone likes the way they change colors.

Does the oxy liner obsorb oxygen or is it just a seal ?
A shopper on Dec 30, 2016
BEST ANSWER: Don't know the technical specs, but every beer I have capped with these turned out fine even if they sat for a while before drinking them.
