Sophico Silicone Fermenting Lids, Waterless Airlock Fermentation Tops Mason Jar Lid Fermenter Caps for Pickles, Kimchi, and Fermented Probiotic Food - 4 Pack, Wide Mouth (Jars Not Included)

These fit wide mouth jars perfectly. I love that they’re one piece, dishwasher safe, easy to use, work well, and cute. They’re made for pickling, so with enough internal pressure, gasses can escape from the little flaps at the top. You could probably fit a straw through the opening too. I use these as a plastic free storage solution and mainly have fruits or leftovers and the seal is enough that nothing dries out in the fridge.

I like these lids. The best of all I’ve used. They work perfectly.. what can I say easy to use on no fuss.

These are perfect for fermenting Good price and easy to use

Work great/ they do lift a little with the buildup of fermentation so you need to remember to “burp” them. Does retain some of the smells in the silicone.

Love these things. Storage capacity - they fit pint & quart wide mouth mason jars perfectly, they’re durable (I’ve washed them many times), used as intended they don’t leak, and it’s handy having multiple colors when the ferments start getting foggy (dill pickles). Plus - no rusty rings! I’d definitely buy these again.

I LOVE these!!! I filled my jars to the top and I probably should have left a little room. Next time I will not fill them so high to where the juice comes out when I push to let the air out. Actually, they seal very nicely. I appreciate the colors so I can tell the difference in jars. I can use them to store things in various size mason jars as long as it is Wide Mouth. They are very easy to clean, don’t take up much storage space and are good quality. I really like them and I will buy another set.

Best product for fermentation I have ever used! And they are so cute too!

Love these for storage. Easy to keep clean and fits well on large mouth jars. Keeps food air tight
