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.

Perfect for fridge storage. Much better than the metal canning lids

They're so much smoother than the metal lids and rings. So for frequent use they're way more agreeable. They're easy on the hand, since the edges are more comfortable for gripping. They're truly leak proof, hold up to daily use, they make the jars better stackable, and they're sleekly attractive. I haven't found a down side. All my storage jars have these lids now. The photo is of our hot cocoa bar. All our “add ins” were in jars with these lids. Daily use by kids no less and they're still going strong.

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.

Fits perfectly on true Mason jars and super easy for jars you use frequently, like powdered milk for your coffee or tea. Not clumsy like using 2-piece lids.

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!

Very disappointed. The description says "one-piece lid" but it does not say one lid. Standard canning jar lids are two-piece, so one-piece fits the product. But the photo shows two lids. So, misleading is all I can say about whoever wrote and approved the description to say the least. The price is high for two lids, and unreasonable for one lid. So Walmart gets a D-minus.

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.

These Ball wide mouth mason jar lids are exactly what I was hoping for. They fit perfectly on all my mason jars with no issues at all, and the seal is tight enough that I've never had a leak—even when storing liquids or tossing a jar in a bag. What I really appreciate is that there's no separate gasket to deal with. It's a simple, one-piece design that just works. I use them regularly for meal prep and storage, and they've held up great with repeated use and cleaning. If you're looking for a reliable, hassle-free lid upgrade for your mason jars, these are a fantastic choice.
