The Black+Blum Rectangular Microwaveable Multifunction Food Box is stainless steel that's genuinely safe to put in the microwave, tested and approved by the Good Housekeeping Institute. A vacuum-sealed lid lock keeps it 100% leak proof and airtight, and the lid can stay on while microwaving, which speeds up heating and prevents splatter. It comes in three nestable sizes for meal prep, food storage, or a daily lunch box, and is dishwasher, oven and freezer safe throughout.
Features
- Genuinely microwave safe steel: Tested and approved to go in the microwave, not something most stainless steel containers can claim.
- Leak proof, airtight lid lock: Keeps food fresher for longer and prevents spills.
- Lid can stay on while microwaving: The lid lock vent lets steam release, so it heats faster than other steel boxes and won't splatter.
- Nestable and stackable: Three sizes nest inside each other, or stack when the same size, for easy storage.
- Dishwasher, oven and freezer safe: Just not the lid in the oven.
