This set includes 10-glass meal prep containers in 2-practical sizes: 5-large 34 oz. containers and 5-small 13 oz. containers. The large ones work well for main dishes or larger portions, while the small ones are suitable for sides, sauces, or smaller meals. Made from premium borosilicate glass, these containers offer better resistance to thermal shock compared to regular glass. They can go directly from the freezer to the microwave or oven without cracking, making them convenient for cooking, storing, and reheating. The snap locking lids are designed with silicone seals to create an airtight closure. This helps keep food fresh for longer and prevents leaks, so there is no worry about sauces spilling in a bag or refrigerator. The lids are easy to snap on and off, and they remain secure during transport. The glass bases are versatile and can be used in the microwave, oven, freezer, and dishwasher. However, the plastic lids should not be placed in the microwave or oven, as they are not heat resistant to that level. Cleaning is straightforward since the glass does not absorb odors or stains. Color: Clear.
