Plastic Lids for Wide-Mouth Jars
Product Review (submitted on December 28, 2013):
I use and re-use them with jars of fermented vegetables. The lids are good for refrigerator storage. No rust after repeated uses like traditional metal Ball jar lids and rings.
One caution is that these plastic lids are not water-tight. Liquid contents will leak out if jars are tipped over or shaken forcefully.
