I have a very few,...and want many more,....of those plastic rings that fit canning jars. I have a very damp storage place that I have to keep my canned foods and dried foods that I've vac-u-sealed in canning jars and the rings just don't hold up well. It also ties up my metal rings when I'd like to be using them during the canning season. So I'd like to buy the plastic ones to use on jars while in storage. Any ideas on where I could purchase them?? Thanks! P.S....I've just finished vac-u-sealing up 18 half gal. jars of hard red wheat that grea in the field ajoining our property! Thats' 125# of wheat! I feel good about that!
