5.0 out of 5 stars Perfect way to store opened canning jars, December 1, 2007

By	B. Anderson - See all my reviews (REAL NAME)

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.

5.0 out of 5 stars Ball wide storage cap, February 17, 2008

By	Tony "lid user" (Los Alamitos, California) - See all my reviews

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?

5.0 out of 5 stars Use THESE - *NOT* the metal lids, for non-canning storage!, July 31, 2008

By	Charles C. Cotton - See all my reviews (REAL NAME)

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.
