Frequently asked questions
How long does food stay warm in a thermos lunch box?+
Quality thermos bento containers (OmieBox, Thermos Funtainer) keep food at safe temperatures for 4–5 hours when pre-heated with boiling water for 10 minutes before packing. Without that pre-heat, expect 2–3 hours.
Is stainless steel worth the extra money?+
If your kid will use it for 5+ years, yes. PlanetBox and LunchBots outlast most plastic options 3–5x. If you expect to replace lunch boxes annually (common with younger kids), plastic is fine.
What size lunch box does my kindergartener need?+
Most 5-year-olds eat a 2–3 cup lunch. Five-compartment bento layouts (Bentgo, LunchBots Cinco) match that volume well. Avoid oversized adult lunch boxes — they encourage overpacking and waste.
Are bento lunch boxes dishwasher safe?+
Most plastic bentos (Bentgo, PackIt) are top-rack dishwasher safe. Stainless options vary — PlanetBox and LunchBots can be machine-washed; OmieBox needs hand-washing for the thermos insert.
