144 Oxygen Absorbing Beer Bottle Caps, 26mm US Standard size Pry-off Black Crown Caps for Homebrew, PVC Free Caps for Beer Bottles

Works great. Sanitize the just before use but DO NOT PRE-SANITIZE.in other words If they get wet, and you don’t use them, they lose their ability to deoxygenate your beer. So discard them.

I love how these bottle caps change color based on temperature. They also seal perfectly keeping the flavor of my homemade beer yummy.

As advertised.

These are really cool! I think the description was a little confusing on the quantity, but I got 144 bottle caps. When the caps get cold enough, they change color. I got these to use with our Mr. Beer kit and used the Red Baron Bottle Capper to cap the beer in glass bottles, instead of the plastic ones that come with the kit.These went on really easily, looked to be in great condition and were absolutely worth it. I liked the color-changing caps so we can see when our beers are nice and cold. Definitely plan on ordering more of these when we run out of our current inventory.

My beer is sealed with these , I don’t really know what could go wrong . No issues so far !

Works well. Fast shipping.

Turned out beautiful and easy to bend

The media could not be loaded. I have ordered several rounds of these traps and they always come in great condition. Sometimes colored crown caps are scraped and the coloring is not solid. Not the case with these caps!
