1. Material safety
No deformation at high temperatures: heat it at will, no need to worry about releasing harmful substances like plastic boxes.
No staining and odor: after containing curry and spicy hot pot, rinse it with clean water, and it will not be dyed "tomato color" like plastic boxes.
Mom party favorite: bring lunch to children, no need to worry about breaking or scratching hands, and no need to worry about "whether plastic is toxic or not".
Comparison truth:
Plastic box: many scratches after long use, easy to hide bacteria
Glass box: heavy! It will be scrapped after falling once
2. High durability
Won't break: your hand slipped on the ground when you were on the subway at work? Pick it up and wipe it and continue to use it.
Won't be crushed: the food is too full and pressed into the bag? Stainless steel's pressure resistance is much better than plastic boxes.
No old use: the surface oxide layer is rust-proof, and it is not a problem to use it normally for more than 5 years.
3. Hot and cold food
Keep warm in winter: the hot soup in the morning is still warm at noon (provided that you choose a double-layer model). Keep cold in summer: Take iced fruits out and they won't melt for 2 hours.
Lazy people's welfare: You can heat them directly on an open flame (only for models without plastic accessories).
Note: Metal cannot be directly put into the microwave! But you can pour it into a ceramic bowl to heat it, or choose a model with a PP plastic lid.
4. Cleaning is ridiculously easy
Grease stains can be washed off with one rinse: Unlike plastic boxes that need to be brushed repeatedly, stainless steel can be cleaned by rubbing it twice with detergent.
Dare to use steel wool: wipe stubborn stains casually without worrying about scratches.
Disinfection at will: Boil in boiling water, steam sterilization, dishwasher, you can do whatever you want.
5. These scenarios are especially recommended
Bringing liquid food such as noodle soup and porridge
Fitness party packs high-protein meals (large quantity and pressure resistance)
Office workers/students who often bring their own meals
Requirement for appearance: ins-style metal texture looks good in photos
Purchase and avoid pitfalls guide
Look for 304/316 food-grade stainless steel (the logo is engraved on the bottom of the box)
Sealing test: Fill with water and shake it upside down, buy it if it does not leak
Carefully choose those with internal coating: there is a risk of coating shedding
