The Black+Blum Meal Prep Box is ideal for anyone who loves meal prepping or eating on-the-go. Made from premium 18/8 stainless steel, this food box is lightweight, durable, and microwave-safe. The airtight, vacuum-sealed lid ensures your food stays fresh for longer, while the innovative lid lock vent allows microwaving without splattering—no cling film needed. The semi-transparent lid makes it easy to see your meals, and the removable seals make for quick, hassle-free cleaning.

This container is also dishwasher, and oven-safe (lid excluded) and is designed for easy cleaning and convenient storage. It nests with other sizes or stacks with same-sized boxes to save space.

-Microwave-safe: These steel boxes are safe to use in the microwave, thanks to the high-quality stainless steel and smooth, rounded design.
-Ensure you do not use in older 915 Mhz microwaves. Always wash all parts with warm, soapy water before the first use.
-Do not place any cutlery, foil, or metal surfaces in the microwave with the box. Avoid heating extreme temperature foods like popcorn or sugar, as these can cause burn marks.
-Heat for a maximum of 2 minutes at a time, stirring and repeating if necessary. The lid lock must be open when microwaving to allow steam to escape.
-Microwave safe up to 1000W. The box may become hot, so use oven gloves or a tea towel when removing it.
-Do not use the box in the microwave when empty.
-Dishwasher, freezer, and oven safe (base only). Do not overfill when freezing to prevent liquids from expanding.
-Leak-proof: The vacuum-sealed lid lock ensures the box is 100% leak-proof and airtight.
-To open, press the button to release the lid lock and pull the lid upwards slowly.
- Avoid using sharp objects directly on the steel to prevent scratches. Clean with warm soapy water and remove the seals and lid lock valve for deep cleaning. Do not use bleach, abrasive cleaners, or scrubbers.
