Stainless Steel Food Storage Containers

Some stainless steel containers can be used in the microwave, depending on their design. Elephant Box has a range of microwave safe food storage containers, making it easy to reheat meals without transferring them to another dish. As microwave compatibility varies by product, we recommend checking the individual product page for the latest guidance before heating.

All products in the food storage collection are leakproof and airtight.

The range covers a variety of sizes from small (ideal for snacks and dips) to medium and large (suited to meal prep, batch cooking, and fridge storage). Exact capacities are listed on each product page. There are a range of sizes available from 50ml to 2 Litres.

Yes — several products in the range are designed to stack, making them efficient for fridge and freezer storage. The Prep & Store Set of 3 nests together when empty. They all stack except the lunch bowls.

Yes. Replacement lids and spares are available in the Accessories & Spares section of the site.

Keeping your Elephant Box food containers clean is simple. All food storage containers in this range are dishwasher safe, or you can wash them by hand using hot, soapy water and a soft cloth. For more tips on maintaining the finish and getting the most from your stainless steel products, take a look at our guide to caring for stainless steel.

Many customers use our food storage containers as an everyday lunch box — they're robust enough for bags and commutes, and the leakproof options handle sauces and soups without issue. If you're specifically looking for a dedicated lunch solution, our stainless steel lunch boxes include compartment options, sandwich boxes, and snack pots designed for on-the-go eating.

Food storage containers are primarily designed for fridge, freezer, and kitchen prep — keeping food fresh between cooking and eating. Lunch boxes are optimised for carrying food on the go, with features like secure clips, compartments, and compact sizing. Elephant Box makes both: browse our stainless steel lunch boxes and snack pots if you need a metal lunch box for work, school, or travel.

Yes — several products work well for children, and we have a dedicated kids range within our lunch box collection. For food storage at home, the smaller containers are a good fit for snacks and portioned meals.

Yes. Stainless steel has a smooth, non-porous surface that won't absorb odours, flavours or moisture, helping to keep your food fresh while remaining hygienic over time. Airtight, leakproof lids further extend freshness by reducing air exposure. Across the Elephant Box range, stainless steel lids use a silicone seal to create an airtight, leakproof closure, the Seal & Go collection features full silicone lids, and the Prep & Store range pairs borosilicate glass lids with a silicone seal. Together, these designs make Elephant Box containers ideal for meal prep, packed lunches and storing leftovers.

Yes — stainless steel handles heat well and won't warp or release chemicals when used with hot food. You can fill containers straight from the hob or oven (allow to cool slightly first before sealing as the steam will interfere with the seal). Just remember they're not suitable for microwave reheating.

Yes — the Prep & Store Set of 3 gives you a nesting set of different sizes, ideal for batch cooking. We also have kitchen bundles in our Bundles & Gifts section if you're looking to kit out a full plastic-free kitchen. Also, the Clip and Seal product comes as a set of three.
