The innovation for more freshness in your kitchen: With the ZWILLING FRESH & SAVE vacuum refrigerator box made of plastic, you can keep food, such as cold cuts, fresh up to five times longer compared to traditional storage without vacuum. The vacuum box comes in various sizes, creating order and clarity in your refrigerator. The vacuum container is freezer-safe, microwave-safe, and dishwasher-safe. It is made from a lightweight, shatterproof plastic that is semi-transparent, allowing you to see what is inside your containers at all times. To help you stay organized, there is the free ZWILLING app. Simply scan the QR code on the lid of the refrigerator box, and the app will automatically notify you in time before your food expires.
