    One possibility is that, any of these jars that were vacuum sealed in the first place, they can easily be re-vacuum sealed with a cheap vacuum chamber/hand pump combo. it’s not an appropriate preservation method for all the kinds of things that originally came in the jars, but will keep dry goods from oxidizing/etc.
