With this environmentally friendly freshness protection set you can now do without the one-time use of cling film. The reusable freshness protection covers are elastic and extremely stretchable. Thanks to the different sizes, they fit on a wide variety of containers or foods. Simply select the smallest possible size, pull it over the container or the cut surface of freshly cut food - done! This way you keep food fresh longer, prevent odours in the kitchen or refrigerator and seal containers air- and watertight. After use, you can simply wash and reuse the freshness retaining lids.
