Stainless Steel Lunch Boxes

A stainless steel lunch box is a reusable metal food container: steel does not hold on to food smells or stains the way some plastics can, and it stands up to daily carrying. This page gathers Calm Eden's stainless steel lunch boxes and bento boxes in round, square and rectangular shapes.

When comparing listings, start with the steel grade where one is named. Most boxes here name 304 stainless steel, and a few name 316, such as the Alloymeal 316 Stainless Steel Lunch Box. Then choose the build: the Mealhold 304 Stainless Steel Insulated Lunch Box is described as insulated and multilayer, while the Mealgrid 304 Stainless Steel Compartmented Lunch Box is a rectangular divided box. Check the compartments, the lid, and the capacity where a listing states one.

The honest limits: a single-wall steel box will not keep food hot for long, and insulated boxes are heavier to carry. Metal containers are generally not meant for microwave ovens, so move food to a microwave-suitable dish to reheat it. Wash with dish soap, rinse and dry before storing.

Our stainless steel lunch box guide compares grades, insulation and compartments. For more kitchen ideas, browse Kitchen & Dining or visit Guides and Tools.
