If you want to STORE food in ball/mason jars, rather than CANNING food, you NEED these.
Here's why:
The two part metal lids & caps that come with the Ball jars are for *CANNING*. These are NOT DESIGNED to be AIR TIGHT! The act of *canning* (pressure cooker, etc) creates a vacuum which seals the metal lid to the jar - the screw part is optional and is to simply hold the metal lid IN PLACE in case the canning fails. They are designed like that so that if the canning process is somehow faulty, and bacteria forms inside the jar, the lid will let the gases escape without making the jar EXPLODE. If you fill a jar up with WATER and put one of these metal lid/screw combos on it, and put it on its side, in a short time you will see it is NOT air or even water tight without a vacuum.
Now, you DO need the metal lids for canning, of course, and also if you're using one of those vacuum sealers with the jar attachment like the FoodSaver (which I recommend).
BUT YOU ALSO NEED THESE PLASTIC LIDS for storing anything else you want in the very handy classic ball/mason jars. The plastic lids ARE water and air tight - so they're perfect for medium-term storage of cereal, cookies, noodles, rice, etc.

If you are going to use your jars to store dry stuff, I highly recommend these lids. However, for liquids, they do leak. I used them to carry some Oriental style dipping sauce to work, and it made a huge mess in my bag. Not a great experience at all.

These are sturdy (long-lasting) and water-tight lids that fit on Ball wide mouth canning jars. They are perfect to use once a canned jar has been opened and will be stored in the refrigerator for a few days or weeks. Also, they make the Ball canning jars more useful as short-term storage containers for soups, etc. because they are so much easier to use than the canning lids and rings. These are a must-have if you use Ball wide mouth canning jars in your kitchen.

Excellent! It is SO nice not to have to fool with the metal two-piece lids and these will not rust. They do need to be tightened well though as they will leak VERY slightly if stored on the side. Maybe just use your brain and keep them upright in the fridge?

These plastic lids come in two sizes, standard and wide mouth, and fit all kinds of canning jars, from the tiny 4-oz to the gallon sizes.
I keep buying them, because I keep finding more uses for them. I store dry beans and many other foods that come in floppy bags or boxes (dry beans and peas, cornstarch, powdered sugar, etc.)after they've been opened, also use them on canned and jarred foods after they have been opened and not used up.
I even use them in my cupboards under sticky jars of honey and molasses to prevent having to constantly clean up cupboard shelves.
These lids have other uses, too, like holding screws, washers, and other tiny parts you might lose while repairing or making something.
Very handy for the whole family!

After reading the reviews, I was hoping that the minority who said that the lid leaks were just those few. As soon as I received the lids, I put them to the test. I filled a 4oz jelly jar (from same manufacturer) with tap water, put the lid on tight and turned the jar sideways. Within seconds, water was dripping out. Some of the reviewers say to use common sense and not put a jar sideways. Well, that's not really the point, is it? A lid is supposed to keep contents in. It is not a matter of common sense, but a matter of not having a mess in your bag if you are like me and prefer to use reusable containers to transport your food/drinks or anything else that may have some liquid. So yes, I deducted one star for the leak factor, but I think I am being generous because, I would have liked the lid to be airtight, and airtight does not mean vacuum sealed as the top reviewer would have you believe. Airtight simply means that air should not come in or out, and your food, though not preserved, would stay fresher longer. Husband says all they had to do was add a little rubber gasket to the lids. How about one piece metal lids with the rubber gasket for even more durability and no leaks? I think all of us would purchase those in a heartbeat!
On the other hand, these lids will serve some purpose. I make my own baby food and these lids are simpler to handle than the 2-part canning lids if you are not canning. And once my baby outgrows baby food, I can use the lids for opened homemade jams that were previously canned in the same jars - they are easy to use and easy to open so even my older toddler can open on his own to spread his own jam (probably the reason they are not airtight). Now I just have to figure out a way to transport to daycare without liquids spilling all over.... Read more ›

I bought some of these caps not long ago when I just ran upon them. I had been looking for a plastic cap with a good seal to use on canning jars that I use and reuse. I especially needed plastic because I make kefir in Ball canning jars and kefir is very acidic causing metal caps to rust. I also needed to be able to securely shake the jar before use without leakage. These caps are well-suited for both purposes. They are also good for use on home-canned pickles, mayonnaise jars, etc, which also are best with plastic due to acidity. Of course, you cannot can foods using these caps, but they can be placed on the jars after canning, or after making jams and jellies, for storage. I recommend these specific caps because I have used them and they serve the purpose well for which they are sold.

LOVE these!
When I purchased the mason jars, I really didn't need, nor want, the lids that came with them....the typical lids with bands. Read more

Three stars for lack of water/air tight seal
Mine are NOT water tight! Which means they are not air tight either. I still use them all the time for storing open jams and pickles...stuff like that. Read more

Good for general storage of upright jars, but not great for transport...
These work great for general storage, especially for dry goods kept in mason jars. As they are one piece, they are easier to use than the standard lids and rings. Read more

Nice
I like these storage caps to put on canning jars after they have been opened. I also use the jars and lids to store dry goods. These are not for canning.

Handy if you're not heat-canning
I use Mason Jars for food storage in the refrigerator and these lids are better than the traditional canning lids for this type of food storage. They seal well.

Bought to replace the Canning caps
I don't use my Mason jars for canning, but rather for everyday use, and preferred doing so with these plastic caps. Quite happy I got them.

Lack of air tightness limits utility
The plastic cap does not have any sort of rubber ring to it, so it is not water tight. And if it is not water tight, obviously, it is not airtight. Read more

More convenient than the band+lid arrangement, but NOT leak-proof
My wife and I have been trying to get away from plastics for storing, heating, transporting, etc. our food and decided that Mason Jars would be a good route to take. Read more
