Since I don't have much company anymore, usually just for the holidays, I store all my extra bed linens in them. I have never had a problem with air getting back in them, but I have had the tabs come off. I forget that you just need to pull apart the bag to open and the tabs are just for sealing. My linen closet looks so much neater. I also have a couple of the bags that are in a canvas holder. They are really big and I like to put the comforters and mattress pads in them.
