Get a slim bento box, not a lunch bag.

The best office lunch box is a slim, two-tier bento that slides into a desk drawer like a file folder.

Lunch bags are for commuters. If you’re eating at your desk, you want something that doesn’t scream “brown bag” and doesn’t take over your workspace. Look for a rectangular bento box — Monbento makes good ones, and even a simple glass Snapware container works. The magic is the shape: flat, about 2 inches tall, and leak-proof. Stainless steel tiffins are another option if you want to skip plastic.

Two things to check first: Does your office have a microwave? If yes, skip insulated bags entirely. If no, you need insulation — and that won’t fit in a drawer, so ignore everything above.

Your drawer will thank you.
