Mason Jar Lids - Compatible with Ball, Kerr, and Other Brands - Vibrant Colored Plastic Caps for Canning and Storage Jars - Airtight and Spill-Proof - Pack of 8 (Wide Mouth - 3.38in)

Works great. Cleans easy and creates a tight seal. The silicone rings come out easily for cleaning. You may have to put them back in place after you take off the lid. Its still functional and great for the price.

I was searching for containers for my homemade yogurt when I saw these lids. Since I already have a lot of pint jars, it seemed like a great idea.Canning lids and rings have gotten so expensive and not always available, and they’re not very convenient if you’re not actually canning.These lids fit my Kerr jars perfectly.I can’t speak to whether they’re leak proof or not for packing a lot inch, but they’re secure enough for my purposes.

I love the bright colors they fit on my jars well with the rubber ring they are made well they don’t leak if you put the white ring on the lid they are easy to clean

These lids are beautifully colored and add an awesome pop of color to my kitchen.However, they are horribly, wretchedly, wickedly difficult to screw onto small 4 oz jars.I am not sure if they are leak-proof yet.

I use these with my mason jars for food prep and left overs. only issue is silicone ring does move some so an extra twist to insure no leaking. Also ring is easily removed for washing. Lid should be hand washed to place in upper rack of dishwasher otherwise it will warp.Great price, ease of use and love the colors.

I should have read the review about this product in advance. These are NOT leak proof, I learnt that the hard way when I was travelling with my smoothies and lemon water using these lids and it leaked all over......they do the job if you are just wanting a cover for the fruit flies not to get into my smoothie but I don't recommend them for travelling since they are not leak proof. Sometimes it's not that easy to screw the lid on.

I am reusing my mason jars to ferment foods like kefir and sauerkraut for the probiotics. This process can corrode regular metal lids and the metal gets into the food. These have rubber rings included for a very water tight seal. I love them.

Good for occasional use. Not for daily use. Very difficult to twist on, and often slipped off after turning lid onto jar. I switched the lids on my dishwasher crystal jars back to the 2-part metal style.PROS:(1) Tight fit(2) Ok for storing craft supplies or other items only used 3 or 4 times a yearCONS:(1) Requires a LOT of effort to twist the cap on or off. I often twist the lid on, as much as I can, and then the lid comes off as I am putting the jar into a lower cabinet. The lid was only barely within the threads on the jar, even though I had turned until the jar resisted and my wrist hurt.(2) Frustrating for daily use items(3) More plastic in the world
