Comes with lots of mylar bags. Oxygen absorbers. And heat sealer. If you are a hunter or got a large garden or some kind of ability to get alot of food all the time then this is for you.. Used it about 45 batches. Changed oil twice In pump so far every 20 runs I changed it. Selling because I do not use it as often as I should.. Can do whatever you like in a full freeze dry run for a test if serious to buy.
