FAQ:

Q: What is the Best Lunch Box for adults?

A: Our top pick is the MEIR Adult Lunch Box, which ticks so many boxes including ample storage space, unique functions, and plenty of color options. If you’re looking to splurge on an adult lunch box that is a bit more compact, however, opt for Modern Picnic’s The Luncher ( view at Modern Picnic ).

Q: Are reusable lunch boxes or bags worth it?

A: Plus, a reusable lunch box or bag means less waste than using a single-use brown or plastic bag for toting your food. And don’t think for a second that lunch boxes are just for kids (although we did find the perfect pick for little ones, too!):

Q: What lunch box is similar to the LAN Bean lunch box?

A: The Fulton Bag Co. Upright Lunch Bag is most similar to the L.L.Bean lunch box in size and features. But the liner on the Fulton bag ripped when we tried to clean it with a sponge, so we eliminated it.

Q: What can you put in a lunch box?

A: Though the lunch box is on the smaller side, it’s roomy enough to hold a drink, a sandwich, multiple snacks, and a few small ice packs. Small food-storage containers or a food thermos with last night’s leftovers can fit inside the bag, too. Note that the lunch box is meant to be carried upright but zipped open while lying flat.
