FROM FREEZER TO OVEN - Make your kitchen more efficient with this silicone ice cube tray with lid! Perfect for broth portions, recipes, meal prep, and portion-controlled meals. In addition to freezing soup, it can also be used for baking. It withstands temperatures from minus 22 to 220 degrees Celsius. ORGANIZE YOUR FREEZER EFFICIENTLY - You can use the meal prep container to prepare several meals at once and freeze them, then pack the frozen cubes into ziplock bags and label them, storing them neatly in the freezer for emergencies, which can save you a lot of time. EASY-OPEN AND FLEXIBLE LID - Our transparent silicone lid has an extra strong seal, ensuring the 4 compartments remain individually sealed, effectively preventing portion control changes and confusion between compartments when the mold is moved. ALLOY STEEL REINFORCED FRAME - The interior is reinforced with an alloy steel frame to further enhance the mold's durability; even if the silicone soup mold is 100% full when moved or stacked, you don't have to worry about the freezer box collapsing. SAFE AND DURABLE, NO WASTE - These silicone broth containers are an environmentally friendly option. They are made from 100% BPA-free platinum silicone, reusable, which demonstrably reduces the use of single-use plastic to protect the planet.
