With the Zwilling Fresh & Save Starter Set 7-piece, you get a compete vacuum set to vacuum food. The set includes a vacuum pump, 2 storage containers, and 4 sealer bags. That's useful, because you can store ingredients you vacuumed or marinated right away. The cordless vacuum pump is lightweight and compact. With the touch of a button, the pump retracts the air out of the bag or box in a couple of seconds. The glass storage containers don't take up much space in the fridge, because they're easy to stack. After use, you can clean the storage containers in the dishwasher. You can charge the vacuum pump with the included USB cable.
