The 5-piece (re)zip stand-up Pack n' Go kit includes our most popular (re)zip stand-up sizes in assorted colors. (re)zip bags are ideal for use at home or on the go. They are food-safe, lead-free and BPA-free. These durable, lightweight bags can be used for snacks, sandwiches, travel, home organization and more. Use them on-the-go for healthy lunches and snacks, or for bulk grocery items without having to change containers at home. The transparent design allows for a quick glance at contents inside, and the double-lock closure provides an airtight seal. (re)zip stand-up bags have an expandable base for easy filling and cleaning. (re)zip bags are freezer safe, perfect for fruit, or soups and stocks. When not in use, the bags nest and compress flat for convenient storage. (re)zips are dishwasher safe in the top rack using low heat. For best results, hand wash is recommended. (re)zips are not intended for microwave or high heat use. One (re)zip replaces up to 300 disposable baggies.
