Oxygen Absorbing Bottle Caps - 120 Count
The bottle caps worked as advertised. They were great.
They worked great.. Kept the beer from getting skunky..
I have used these for all my bottles through the years with never any failures. However, they use to come in a bag with a “gross count” that is 144 caps. Now I see Midwest only provides the 120 count bag.
about 20% would not attach and another 20-30% that seemed to seal, did not seal well enough or hold long enough to develop carbonation. May work on other bottles but not so good on corona bottles.
