FoodSaver Fresh Containers are designed for fridge, pantry and on-the-go use to keep food fresh up to two times longer than non-vacuum methods. The containers seal in freshness of foods stored in the fridge, pantry or on the go to help reduce food waste, so you can enjoy what you ordinarily would lose to spoilage. They're ideal for fresh fruits, berries, produce, leftovers, pantry items, meals, snacks and more. The containers help simplify chaos in the kitchen and fridge with their stackable, nestable design to keep everything neat and organized. Because they're made with a clear BPA-free Tritan material, it's easy to see what you're looking for, and they're safe for the microwave and dishwasher so reheating and cleanup are super easy. Made for ultimate everyday fridge and pantry storage with the promise of freshness, these containers are designed for use with any FoodSaver Food Preservation System or Handheld Sealer (sold separately) to create a unique, airtight seal.
