Kombucha Jar Covers | 3-Pack Fabric Round Covers Perfect for Brewing | Fit Wide Mouth Mason Jars Up to 120mm

Large glass jars

They are excellent covers. Substantial and easy to use. Fit well. A bit expensive for what they are, but do the job well.

£15 - It's covers only - it's a joke. Returning it.

It works well with keeping little fruit flies away. There are small gaps between the cover and the jar though so it's not ideal. Still in search for a better solution

These do not work because they do not keep out fruit flies so now my kombucha scoby is ruined. I've gone back to my muslin and elastic band. They are really expensive too. I thought the cost included a jar as well. That's probably my fault for not reading carefully enough but the picture made me assume that.

Great product just bit expensive

I bought these for my kefir jars, brilliant idea. Would recommend

These covers are so very easy to use.Just fit over the top of the jar and tighten the cord.Washup is a breeze as you can just rinse under running water or wash with the rest of your dishes.

I've been using rubber bands and kitchen towels for so long, I can't believe what an upgrade these are! I should have bought these years ago!! I'm going to order more for my kefir jars. They fit the gallon jugs perfectly and do an amazing job keeping out fruitflies and dust. Very pleased with this simple upgrade to my kombucha brewing set up.

Very easy to use and still allows air to circulate during the fermentation process. Better yet, acts as a filter when pouring and you can tap the particles back into the remaining liquid, then rinse clean to start again.

These are amazing covers! Didn't feel like dealing with rubber bands and coffee filters so I picked these up. Will definitely be back for more if needed!

Tried it, fitted my large opening jar, tightly though, but good. It is a 1 Gallon jar. Very easy to clean. No bugs in and enough air flow. A little expensive for the product, but overall satisfied.
