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)

Works great! My jars are the Walmart brand 32 oz size and they fit perfect! I used to make my yogurt!

Bought these as they were one of the ones recommended by a fermenting pro as being safe and easy to use. Make sure you read the instructions on the box for using them though. I automatically assumed that they 'auto-vent' when the pressure builds up. Discovered one morning that the kimchi I had fermenting had lifted the lid and there was kimchi juice all over the table. Must have been quite a show! THEN I read the box and realized that you are supposed to press down on the middle of the lid once the fermenting starts once or twice a day (or whenever you see it starting to bulge) and THAT is what releases the gases. Lesson learned. But sure proved to me that these lids seal on the jars pretty darn well! Very happy with them.

Trouble free. Easy to clean.

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.
