Materials

• 18/8 food-grade stainless steel

Common claims

• BPA-free
• Leak-resistant compartments
• Dishwasher safe

Concerns / watch-outs

• Not microwave safe
• Some models have plastic or silicone dividers inside; verify all food-contact surfaces

Stainless steel bento boxes are one of the safest lunch container formats. The divided compartments keep foods separate without any plastic-food contact.

Cleaner alternatives

Materials

• Borosilicate glass
• BPA-free plastic snap lids

Common claims

• Oven, microwave, and freezer safe
• Non-porous glass
• BPA-free lids

Concerns / watch-outs

• Lids are typically polypropylene (PP) — avoid microwaving with lid on
• Glass can break if dropped on hard floors
