    Stainless Steel Lunch Boxes Built to Last

    Looking for a stainless steel lunch box that survives the school bag, the work commute and years of daily use? Our range brings together trusted brands Bentgo and Oasis, with options for kids, teens and adults.

    Stainless steel is a durable, long-lasting alternative to plastic lunch containers. It won’t absorb food smells or stain from curries and pasta sauces, and it’s easy to keep clean.

    Leak-proof and microwave-safe options

    The Bentgo Stainless Steel Leak-Proof Lunch Box (1200ml) has a secure seal for packing wetter foods without spills. It’s ideal for larger lunches and adult appetites. For reheating at work or school, the Oasis Microwave Safe Stainless Steel Containers come in 500ml, 700ml and 1.1L rectangular sizes and a 680ml round. They’re a great fit for leftovers, meal prep and salads.

    Bundle and save

    FAQS

    Are stainless steel lunch boxes safe for kids?

    Yes. Our stainless steel lunch boxes are made from food-grade 18/8 stainless steel and BPA-free materials. They’re a safe, non-toxic choice for school lunches.

    Are stainless steel lunch boxes better than plastic?

    Stainless steel doesn’t stain from foods like curry or tomato sauce, and it doesn’t hold onto smells. It also won’t crack or warp over time like plastic can, so one box can last for years.

    Can I put a stainless steel lunch box in the microwave?

    Most stainless steel containers aren’t microwave-safe. Some products in our range are specifically designed for microwave use, and they’re clearly labelled “microwave safe.” Always check the product page before reheating, and remove any lid that isn’t marked microwave-safe.

    Are stainless steel lunch boxes leak-proof?

    Many of our stainless steel lunch boxes have leak-proof lids with a silicone seal, which suits yoghurt, dips and saucy meals. Some containers have vented lids designed for reheating instead. Each product page lists whether the lid is leak-proof.

    Are they dishwasher safe?

    Many stainless steel trays and containers are top-rack dishwasher safe. We recommend handwashing lids and silicone seals so they keep sealing well. Coloured or painted exteriors also last longer when handwashed. Check the care instructions on each product page.

    Do stainless steel lunch boxes keep food cold or hot?

    A standard stainless steel lunch box isn’t insulated, so it won’t hold its temperature for long on its own. To keep food cool until lunchtime, pack it in an insulated lunch bag with an ice pack. For hot meals, try an insulated food jar.

    Can I put my stainless steel lunch box in the freezer?

    Many stainless steel lunch boxes are freezer safe, which is handy for meal prep. Check the product details to confirm before freezing.

    What size stainless steel lunch box do I need?

    Around 500ml suits snacks and sides. A 700ml container fits a single meal for most kids. Teens and adults usually prefer 1L or more for a full lunch. If you like keeping foods separate, look for a lunch box with compartments or a removable divider.

    How do I clean a stainless steel lunch box?

    Wash it in warm, soapy water and dry it fully before storing. To remove stubborn residue, soak it in warm water with a little bicarb soda. Avoid steel wool and harsh scourers, as they can scratch the surface.
