Score breakdown
Here's what we'd tell a friend
What you should know first
There's no insulation โ food reaches room temperature by lunchtime. At $57 for a stainless box, you're paying premium for material safety (9.8/10), not temperature control.
Go for it if...

PlanetBox
Tops the category on material safety (9.8/10) โ worth checking price value before buying.
Key insights
We dug through 44 reviews โ the 18/8 stainless steel construction with no plastic food contact earns a 9.8/10 on material safety โ zero BPA, zero coatings, the cleanest material story in this lunch box comparison โ but at $56.96 there's no insulation and the dividers are fixed, making this the right box for school-age kids whose parents pack only room-temperature foods and want a lifetime-durable container

The questions we hear most about this lunch box.
Keep your PlanetBox Shuttle Lunchbox performing at its best
Wash all compartments with warm soapy water after every use โ food residue left overnight causes stains and odors that become permanent.
Remove and wash the silicone gasket or seal around the lid separately โ this is where food particles and mold accumulate most.
For stubborn stains or odors, soak in warm water with baking soda for 30 minutes before scrubbing.
Store with the lid slightly ajar when empty so air can circulate and prevent musty odors from building up.
Avoid using abrasive scrubbers on stainless steel compartments โ they scratch the surface and create microscopic grooves where bacteria can hide.
Check latch mechanisms and seals regularly for wear. A degraded seal means leaks in your bag โ replace the gasket annually or when it shows cracking.
Pro Tip
Check latch mechanisms and seals regularly for wear. A degraded seal means leaks in your bag โ replace the gasket annually or when it shows cracking.
