Absolutely tight. Design like that. Best alternative for high-priced (and not so dense) Tupperware bowls. Suitable both as a storage box for all kinds of food (coffee, cappuccino, Kaba, sugar, cereals, raisins, pasta), as Restebox (for canned beans, peas, tomatoes, for leftovers of all kinds) as well as a freezer (for leftovers like sauces , fresh fruits such as raspberries and blueberries, and for example also for ground beef). And also as a lunch box can be used, even take in soups or already dressed salads with at work.
