The MagicBag™ by Smart Design Cube X-Large Vacuum Sealed Closet Organizers make it easy to store bulky items and keep them clean. Just pack your items, zip the bag with the easy-grip slider, and vacuum out the air using the one-way valve. The clear, reusable bags protect your belongings from water, dirt, and odors. Each airtight bag saves space by shrinking your items to create up to three times more room in closets, under beds, or in storage areas. Great for bedding, pillows, comforters, and seasonal clothes.
