LunchBots are the best lunch boxes for real portion control

The best lunch boxes with removable dividers are LunchBots stainless steel containers and Bentology’s customizable bento boxes. For adults, LunchBots wins; for kids’ lunch boxes, Bentology is the more flexible option.

LunchBots makes meal packs with actual removable dividers—not just fixed compartments. You can slide them out and reposition them to make one big section for salad and a small one for dressing, or split it evenly for a sandwich and fruit. Stainless steel is durable, easy to clean, and doesn’t hold smells. The only real downside is that they’re not leak-proof, so wet foods need a separate small container.

If you want something with more adjustability and a little more structure, Bentology bento boxes come with movable dividers that snap into different slots. You can reconfigure the interior in seconds, and they have lots of inserts like small sauce cups and fork holders. They’re also cheaper than LunchBots and dish washer-safe (top rack). The plastic builds aren’t as premium, but they hold up fine for daily use.

Personally, I’d skip anything with magnets—PlanetBox looks slick but the dividers shift around in a bag. For adults who want to control portions without carrying five Tupperware containers, LunchBots is the answer. For a kid’s lunch, Bentology gives you the freedom to change things up every day without buying another box.

Whichever you pick, buy one with a removable tray or divider system that’s actually simple to rearrange. Otherwise you’re just paying for compartments you’re stuck with.
