Our biggest lunchbox: two 18.5 × 13 cm steel layers plus a snack container, 1800ml in all. Built for long days, meal prep and big appetites.
They don't pop open, the contents don't spill & they still look like the day I bought them (maybe 5+ years ago).

Questions
Can I pack yoghurt or dressing?
Not loose, as this box isn't leakproof. Pack wet food in an airtight dipper inside the box.
Is it dishwasher safe?
Yes.
Can it go in the microwave?
No. Stainless steel can't go in the microwave. Warm the food first, then pack it.
Will it dent if it's dropped?
A hard drop can leave a small dent, but it keeps working for years.
