LunchBots Large Trio Stainless Steel Lunch Container -Three Section Design for Sandwich and Two Sides - Metal Bento Lunch Box - Eco-Friendly - Stainless Lid - Aqua Dots

We've had similar lunchboxes from this brand in a smaller size (medium) for 10 years, and they're still good as new, which is hard to come by these days. They're a little expensive, but well worth it. I got super excited about this larger size, as it's a better fit for older kids and adults. The main compartment is very generously sized, and even the smaller ones are about 3x3, which has ample room for dippers, a small dip or dressing container, etc. I ordered a similarly sized container from Planet Box, and was surprisingly unimpressed by how much it can hold. I like that this design uses up all the available space. The containers aren't completely leak proof from one another, but we just pack with that in mind.
