The Black+Blum Large Stainless Steel Square Lunchbox is built for big appetites and batch-prepped meals. With a generous 1.4-litre capacity, it’s ideal for main meals, large portions or storing leftovers. Made from high-quality stainless steel with a leak proof, vacuum-sealed lid, this lunchbox is designed to go from fridge to microwave to table with ease.

The semi-transparent lid lets you check contents at a glance, while the vented lock system allows you to microwave your food without removing the lid. Lightweight yet tough, the box is oven-safe (without the lid), freezer-safe and top-rack dishwasher safe.
The container is made from premium 304 stainless steel with a BPA-free polypropylene lid and a silicone vacuum seal. The lid includes a built-in vent lock to reduce splatter when microwaving. The seal is fully removable for easy cleaning, and the container’s square design makes it easy to stack with other boxes in your fridge, freezer or cupboard.
