Ball One-Piece Leak-Proof Wide Mouth Storage Lid, Plastic

My new favorite way to store leftovers in my fridge. Wide mouth jars have an opening large enough to fit my hand through for when I'm washing dishes. These plastic lids don't rust or come apart when you open the jar. Two quart (64oz) jars are perfect.

Fits perfect on my ½ gallon Ball canning jars, although I would not use these for high-temp canning. I am using them for pickeled eggs in the fridge. I flip the jars each day and I am into day 4, so mine have spent at least 48 hrs upside down in the fridge without a drop of a leak. I would also use these lids for storage of dry goods like beans, lintils, rice, oatmeal, etc.

i will buy these again. they are the best ive purchased and i use ball and other brands daily. the lids are thicker, with a seal that both string but easy to remove. im older and dont have a tight grip.

These lids work very well. I have purchased other lids online which leaked, even with insert seals. The Ball lids were a bit pricey, but worth the extra few cents to ensure a truly leakproof seal.Tru

It doesn't matter if you're using these lids for tomatoes you're storing in the freezer or spices in your regular storage area - their reliability is too notch!

They seem to work fine on Ball brand jars. Both pints and quarts. You need to make sure you screw them on tightly. But I had trouble getting it to close on a Ball jelly jar. There seemed to be a little moisture coming out when I shook it. I also tried it on an Atlas brand jar, but it leaked on that one. I have not tried it on other brands yet. They are definitely better than the white caps. But now I have a bazillion of the white ones and don't know what to do with them? Perhaps the company should let us trade them in and get a discount on the new brown ones? Ball, are you listening?

what I did not expect with this product is that it wouldn't fit other mason jars besides the ball brand wide mouth. the only mason jars that this product fits is the ball brand. the mason jars that I was looking to cap they didn't fit not one not one wide mouth non ball brand mason jar. I am grateful that I had ball brand jars 64 Oz jars that only had the drinkable tops these lids fit perfect. I was grateful instead of discouraged for the purchase. they appear to be airtight and sealed nicely on my 64 Oz Ball mason jars.

Used for years and keep buying more, but recently noticed plastic was shredding from grooves and that is a concern. Not sure if it's something I did, so am wondering if anyone else has seen this? The whole point was to have LESS plastic in food as possible!

This review is for Ball One-Piece Leak-Proof Wide Mouth Storage Lid, Plastic: I was expecting a better product from the Ball Company'. I am disappointed. The lid is a Polypropylene plastic lid. There is a groove that the top edge of the jar fits into. There are no additional seals like a silicone ring or piece that the top edge of the glass jar compresses to for a watertight seal. I added water to the har and put on the lid and inverted the jar. Guess what happened. IT LEAKED. I suspect the others in the box will leak too. I cannot consider the product a good value.

I like the color but they aren't even close to being leak-proof. Luckily, I didn't trust the leak-proof claim and put this jar of pickled beets for a friend in a sealed bag.
