Lessisbest...........I was never interested in the Food Saver thing 'cause you can't reuse the plastic, but I didn't know you could use it on jars. That would be great!

KayLR.....what kind if lids do they have?
Even if you decide not to use all of them, I'm sure someone at a place like Goodwill would love to have them.
Oh.....and if they are really old and you found them at work, is there any reason to think they shouldn't be used for food?
