Perfect for comforters and blankets, pillows, patio cushions, sweaters and jackets, and other bulky items, this set of three vacuum-seal bags helps create extra storage space. To use, simply add the items to be stored, zip up the bag using the easy-to-seal Sure-Zip slider, and remove the air that creates bulk using a household vacuum. The patented one-way valve works with any standard vacuum-cleaner hose. The bags not only compress bulky items for more compact storage, but they also create an airtight seal for ultimate protection from dirt, moisture, mildew, bugs, and odors.
