ITW Space Bags are vacuum storage bags for storing everything from bulky seasonal clothes with this quilt extra. Start packing your bags and use a vacuum with a pump to suck the air out of bag space saving. Stay organized and triple the storage space. ITW Space Bags not only protect clothes against dirt and insects, but are water and air tight to keep moisture and prevent molding. Be constructed with multiple layers of nylon and polyethylene, which makes them very durable and reusable for your seasonal needs.
