Are bento-style lunch boxes leak-proof for wet foods like yogurt?

Documented leak-proof ratings vary by compartment and by brand. Bentgo and OmieBox both publish leak-proof or leak-resistant claims for their main compartments, but a separate small container is still the safer choice for very liquid foods like soup broth.

Is stainless steel better than plastic for a school lunch box?

Neither is strictly better; they suit different needs. Stainless steel resists stains, odors and cracking over years of use, while plastic bento boxes are lighter and their molded compartments keep foods separated more precisely.

How do I keep a hot lunch warm without a microwave at school?

A box with a genuine vacuum-insulated food jar, like the OmieBox, is built specifically for this. Filling the jar with hot food right before packing, rather than reheating cold food, keeps it warmer for longer.

What size lunch box does a young child actually need?

Portion sizes documented for bento boxes like the Bentgo are generally sized for ages 3 to 7. Older children or bigger appetites are usually better served by a larger box like the LunchBots Cinco rather than a second small box.
