Stainless Steel Bento Lunch Box with Inserts

Important Note on Food Storage Materials

When I’m choosing food storage and lunch containers, I avoid plastics that contact food (because of concerns like BPA, BPS, phthalates, and other additives), per- and polyfluoroalkyl substances (PFAS) used in coatings, aluminum as a direct food-contact surface, heavy metals like lead and cadmium, and materials that rely on chemical finishes or nanoparticles. I specifically look for stainless steel and glass components that come into contact with food.

Product Description

This stainless steel bento lunch box comes with multiple inserts, making it versatile for packing meals with different foods separated. The food-contact surfaces are stainless steel, a non-reactive metal that doesn’t require coatings to perform or leach chemicals into food.

What I Like

I like that food sits directly against stainless steel — no plastic liners, no coatings, and no PFAS-based finishes. Stainless steel is durable, doesn’t absorb odors or stains, and doesn’t react with most foods. The compartmentalized design makes it practical for lunches, meal prep, or kids’ meals.

Things to Keep in Mind

Some components like lids or seals may include silicone or plastic elements for locking and leak resistance. While those don’t touch the food directly, they’re still part of the overall system. If you want completely plastic-free contact surfaces, this still keeps the food against stainless steel, which is what matters most for contamination concerns.
