Space Bag Giant Combo - Set of 10 - BEST BUY!ITW Space Bag BRS-59112 Storage Bags, 2 Pack - 2 Extra Large Size BagsITW Space Bag BRS-6239 Storage Bag Combo Pack: 3 Pack - 1 Medium Size, 1 Large Size and 1 Extra Large Size BagI could only get these things to work about half the time...And even then they would seal for a while and spring a leak later.So now when I need to pack up stuff for the winter I just grab a 30 gal. trash bag, load it up and sit on top of it to squish out most of the air. After twisting the top and tying a knot in it, I get cheap and compact way to store bulky items.
