lunchbox bento

Many bento boxes include a removable 3-compartment tray with an optional divider to create a fourth compartment. Note that the optional divider may not form a leak-proof seal for very juicy or liquid foods.

Capacities vary widely across models. Examples from listings include small trays around 3.33 cups, several options near 4.9–5.15 cups, a larger 54‑ounce salad bowl, and an insulated sack listed at 9 quarts. Check the product specs to match capacity to your portions.

Some bento containers include a removable ice pack to chill the tray. Insulated lunch bags use thermal linings and insulated walls; listings commonly describe them as keeping food and drinks at temperature for 5+ hours.

Materials shown across items include ABS (Acrylonitrile Butadiene Styrene), polypropylene, generic plastics, polyester canvas, and polyester fabric used for soft-sided bags.

Listings target a range of ages: some child-focused boxes list "about 3 years and up," others note "8" or "10 years and up," and several items are labeled for "All Ages."

Examples include a 54‑ounce salad bowl and compartment trays that list a 10‑ounce main topping compartment, two 5‑ounce compartments, plus a leak-proof 3‑ounce dressing cup.
