Black + Blum STEEL FOOD BOX - Set

Important Notes: Please consider the following points for optimal use. Use microwaves up to 1000 W. (Do not use in older 915 MHz microwaves.) Larger dents or deep scratches may render the box unsuitable for microwave use, so please be cautious. Ensure that you heat only one box at a time for a maximum of 2 minutes before stirring and repeating the process. Heating for more than 2 minutes in the microwave may cause the polypropylene lid to warp, compromising its leak-proof capability. Avoid placing additional metal items such as cutlery or aluminum foil in the microwave, as well as contact with metal surfaces in the microwave or the microwave wall, as this can lead to sparking or burn marks on the box. Please note that heating very oily or acidic foods (e.g., tomato soup) can cause stains and even burn marks on the lids. Use the glass turntable. Do not use the box in combination ovens or microwaves with multiple functions, as these may sometimes have hidden metal parts that can create sparks when in contact with the metal container.
