BLACK+BLUM: Stainless Steel Lunchbox 600ml

The Black+Blum Stainless Steel Lunch Box (600 ml) is a compact, portion-friendly evolution of the brand’s bestselling steel container. Designed as a 3-in-1 solution, it lets you transport meals securely, cook directly in the oven, and store pre-cooked dishes in the freezer—all in one durable, beautifully minimal design.

Crafted from high-quality stainless steel, this plastic-free lunch box blends vintage utility inspiration with a modern aesthetic that ages gracefully over time. A vacuum-sealed silicone valve ensures a secure, leakproof closure, while the included stainless steel fork and silicone strap add everyday practicality.
