The innovative freshness idea for your kitchen: ZWILLING Fresh & Save Bowls, the revolutionary sous vide system for preparing, cooking, serving, and storing. The three glass bowls are ideal for preparing and serving small delicacies like overnight oats or larger salads and Buddha bowls directly in the bowl. Or you can vacuum seal food and then store it in the refrigerator or freezer. Thanks to the vacuum lids, this process is quick and easy, and food stays fresh up to five times longer. And because the lids also fit the Staub Ceramique bowls (12, 18, 24 cm, without handles), you're even more versatile. Another advantage of the lids is that you can easily stack your bowls without having to use annoying foil.
