AIEVEFermentation Lid, 4 Pack Fermenting Lids Fermenter Cap for Wide Mouth Mason Jar

Worked well on fermented pickle recipe. Fit smaller and large mouth jars I used.

I have no complaints on these rubber canning tops. They come in beautiful colors in set of 4. They work exactly as specified. Thanks 👍

Perfect for us forgetful folks. No more exploding jars from built up pressure.They fit perfectly and wash up great.

There are a bunch of different fermentation lids out there, but these are the simplest. Super easy to use, as they're one piece and fit great!I am a little unhappy with how the package arrived, however. The box and instructions/recipes came extremely damaged and coated in what smells like laundry detergent. I initially thought this was a result of a shipping incident, as this product came in the same box as a bubble gun I ordered for my nephew, but the box the bubble gun came in and the bottles of bubbles enclosed were unopened and undamaged, so I'm unsure where the filmy soapy residue came from initially. Assuming that was a one off, I'd recommend.

Worked very well. I've been making kimchi for ages and it's really nice not to have to check it so often. The ferment did come out the opening making it necessary to have a plate underneath.

Good fit, easy to use, seals well. Good for use when fermenting vegetables.

Simplified kraut making. Good seal on canning jars.

Fast shipping, seems to work ok
