Use THESE - *NOT* the metal lids, for non-canning storage!,
This review is from: Ball Wide-Mouth Plastic Storage Caps, 8-Count (Kitchen)
If you want to STORE food in ball/mason jars, rather than CANNING food, you NEED these.
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.

Thank you so much.... I have been using the metal lids to ferment and culture foods, wow. Oxegyn isnt a good thang for this type of stuff. Thanks I would have never known. Thanks much! The metal lids were a hassle anyway, always missing a piece or so.

I'd like to use these on half pint (8 ounce) jars - will these fit?
Thanks so much :)

In my experience with the plastic lids, most of them are NOT air tight and leak proof. Was taking some grape juice to my daughter for her to put in her freezer -- a few tipped over in the box -- what a mess. Lost the 4 jars that tipped over as they totally leaked out.
Used Ball jars to store some rice and grains ... all of the plastic lid jars ended up with weevils that came from some flour that wasn't protected.
I'll take the regular canning jars lids any day.

Sased-These are WIDE MOUTH, for the half pint jars you need the regular mouth. I use the regular mouth ones all the time on my 8oz jelly jars and half pint pickles that I canned and then opened and now store in the fridge with these plastic lids instead of the lid I canned them with plus a metal ring.

These are fine for what they are, but they are absolutely not air and water tight -- there's no gasket of any kind.

These are NOT leak-proof or air-tight. I discovered this after a leak in my bag. Other users have had similar experiences. Be cautioned!

I went to a Science day exhibit & they said the larvae of the weevils are already in the cereal we buy. The solution is to freeze flour, cereal, etc. for a day or two, can't remember the exact amount of time but I'm sure you can Google & find the answer. That kills them, then no problem.

can they be used for freezing salsa and such? how about using a bit of saran wrap and then the cap?
