This is the storage container that keeps food fresher for longer thanks to a built-in vacuum that pumps out air at the touch of a button. Vacuum storage removes the air surrounding food, significantly extending its shelf life by inhibiting bacteria growth and sealing out moisture and insects. Unlike lesser food-preservation systems, this reusable container requires no manual pumping nor wasteful disposable plastic bags. Instead, a motorized pump in the lid quickly draws air out of the sealed container, creating an airless, moisture-free environment that helps prevent lettuce from wilting, bread from growing stale, and wet and dry leftovers from spoiling. The durable, clear polypropylene polymer cover resists scratches and allows you to see the contents within. The base of the unit is dishwasher safe. Requires two C batteries.
