    1. Yes! They work!!  star rating

      Posted by Missy Hinegardner on Feb 13th 2018

      We use OAPs for our dehydrated nuts/seeds. They keep them fresh and crunchy. We soak/dehydrate in the winter so we can go out and have fun in the spring/summer/fall. All of our nuts/seeds stay fresh and healthy for many months as we rotate through them. They are also a great insurance policy for fresh items should we get hit with a winter storm--we are prepared if store deliveries are interrupted etc. PackFresh has very helpful information regarding use etc. Worth your investment!

      this is the second batch of scavengers I've been using, and so far no fails. Great product, great price, well packaged and fast shipping. Very happy with it

      These worked great for dried canning. It made the job so easy that now I have a nice little stash of beans, rice, instant potatoes, noodles and powdered milk. In a few hours all of my Mason Jars were sealed
