10 Pack Plastic Wide Mouth Mason Jar Lids for Ball, Kerr and More - Multicolor Storage Caps for Mason Jars, Canning Jars - Leak-Proof, Dishwasher Safe & Food Grade

Nice product, no warping from the dishwasher. Great for use after opening home canned foods and storing dry beans and rice. Easy to grip, no struggles, rubber gasket that seals air out, accurate size for Ball and Mason jars. Bright cheery colors. I like to take soups and fruits in juice to work in pint jars, no one of these has leaked yet.

Love these! They're used for Mason jar meal prep for the week. They're so much better than metal lids. Perfect fit for wide mouth jars. Tight seal. No leaks. Fun colors. Well-made. Dishwasher friendly.

We store a great deal of food in Mason jars in our fridge and these are great lids for them. Colorful and secure. Helpful and useful. Great purchase. Would recommend with 2 thumbs up.

These lids do the job, which for me is mostly replacing plastic containers for refrigerator (food prep and leftovers) and dry food storage (baking products, snacks, etc.). [Also trying to use glass vs. plastic for food storage to eliminate one more layer of toxicity in food.] I find the "seals" to be optional, really, because the lids tighten nicely and fit the threads of both the Ball and Kerr jars I have. However, I am using them because they are easily inserted and are one more layer toward ensuring less air in the jar. [After a couple months I will check for that usual negatives of plastic used in storage: odor absorption/smell/stickiness.] My only slightly negative comment is that the colors are a little more subtle, and the lids have more of a matte finish than a smooth finish, which I prefer. (The lids I have ordered in the past were no longer available.) I am interested to see how these stand up to everyday use during cooking, etc. Hopefully they will wipe off easily.

If you are like me and use the larger mason jars to store food items in the fridge, these jar lids are perfect. The canning lids that come with the jars are great for canning but not much else as they rust easily. I use the mason jars to store such things as washed blueberries (they stay fresher longer), sourdough discard, buttermilk (from making butter), etc. These plastic lids were a relief from the rusted metal lids, fit snugly and tighten easily.

These are great, and the colors are cool and fun. No scratches that end up rusting, like the metal Kerr or Ball lids. The silicon rings seal the jars very well - liquids don't leak even if the jar it turned upside down.

When doing homemade fermented pickling in my wide-mouth quart mason jars, I had been using the regular canning lids. Even though those metal lids are coated on the interior, eventually they would always discolor or even corrode due to the high salinity. I bought these to try out as a replacement and so far they are working great and seal well. There is an insertable silicon seal on the inside you have to insert and it can also be removed for easy cleaning. I currently have jars of kimchi, sauerkraut and sourdough starter using these. Since I had "extra" lids, I did drill holes in the center of 2 of them which was easy to do. This was so I could insert an sealable silicon "grommet" (https://www.amazon.com/dp/B0FM826SL2) into them and then place an airlock into that grommet. I am using these for "active" fermentation and have some homemade hot sauce in those.

These are great lids! They come with a plastic seal which makes the lids nice and tight. I also love the variety of colors too.
