The Storage vacuum-seal bags help create up to three times more storage space in the closet or under the bed. To use, simply add the items to be stored, “zip” up the bag easily using the Zip slider, and remove the air that creates bulk using the vacuum pump provided or a household vacuum cleaner. The bags not only compress bulky items for more compact storage, but they also create an airtight seal for protection against dirt, moisture, mildew, bugs, and odors. The vacuum bags are perfect for sweaters, jackets, blankets, pillows, and other bulky items. It is made from multiple layers of polyethylene and nylon, the bags offer see-through visibility for finding items quickly, plus their durable design means they can be reused year after year.
