Title: Can't keep a seal
Review: We love our FoodSaver, and use it daily with the plastic bags and especially mason jars for long term storage. But I needed something larger for storing grain and other staples.So I had high hopes for these things (and paid a good deal more for them than the price given here). Even new, every one of them has failed to keep it's seal over the long term. I filled one with brown sugar -- I might as well have left it out in the open, it's now rock hard.
