Fermentation Lids, Mason Jar Lids, Airlocks for Fermenting, Fermentation Kit for Wide Mouth Jars- Stainless Steel Wide mouth Mason Jar Fermenting Lids for Making Sauerkraut Pickle Hot Sauce (4)

Came packaged well and easy to put together. The caps are a little hard to get off, but other than that I think had less growth of anything else on top of the brine than when using a coffee filter. The lid seals are great and just don't fill jar so high that you can't get the stem of the airlock to seal into the o-ring in the center.You can use the lid center o-ring cap to seal it and put in fridge if want. But I just use my regular mason jar lids. Liked them enough to buy a 2nd set.

These lids fit my mason jars perfectly. I love that I no longer have to put a drip tray under any of my ferments and I no longer need to "burp" the jars. Another plus is that there is no longer any chance of kahm yeast growth due to the air lock.

They fit wide mouth glass jars, as promised. The gaskets are easy to install, although I'm not sure what the point of having the little gasket cover is since it seems to pop out on its own. Not like I planned to use it anyway.

They work well

These are so fun! I'm new to fermenting and these help the excess liquid be contained. They seem to be well-made and fit well with the accompanying lids.

Easy to use and easy to clean.

This worked. I made sauerkraut in jars and it turned out great!

Used these airlocks for many fermented veggies including kimchi, carrots, cauliflower, and more.
