Black+Blum Stainless Steel Microwaveable Round Lunch Box

For people done with stained, warped plastic. The body is 18/8 stainless steel, which will not hold color or smell the way plastic does, and the lid is vacuum sealed with silicone to stay leakproof and airtight. At 950 ml it takes a full single-dish lunch: a grain bowl, pasta or leftovers. The catch is the microwave: only some parts are rated for it, so check the care guide before reheating, and put the lid on the dishwasher's top rack only. Round and about 8 cm deep, it sits flat in a tote better than in a slim backpack.
