- Safe food-grade material: The food cube container is made of professional quality food-grade silicone that is odorless and BPA-free, suitable for the whole family. The smooth silicone surface is easy to clean and is safe for dishwasher, freezer, and oven use. Not microwave-safe due to the stainless-steel frame. - Reinforced frame: The soup storage container is reinforced with a stainless-steel frame for extra stability. The soup tray will not tilt when filled with liquid meals, and you can place the tray in the refrigerator without tilting. - Perfect serving size, easy to stack: Each silicone tray compartment includes two fill lines: 125 ml (4 oz) and 250 ml (8 oz), allowing precise portioning of broth, soup, sauce, and other measured liquid meals. The compartments are designed for easy stacking. - Large freezing tray with lids: The reusable silicone tray comes with clear, tight-fitting lids that provide an airtight seal, keeping stored food fresh while preventing odors and foreign tastes. The lids remain easy to open. Use scenarios: - Meal prep and quick lunches: Freeze broth or soup in 4 oz or 8 oz portions, then pop out a portion as needed for a quick, reheatable meal. - Sauces, dressings, and baby foods: Portion and freeze sauces, dressings, or homemade baby foods in consistent sizes for convenient use throughout the week. - Travel and on-the-go containers: Prepare liquid meals or smoothies in measured portions and store with intact freshness, then take along without spills or flavor transfer.
