Lunch boxes aren't just for kids! As more people are back working in the office, lunch boxes for adults are becoming more popular. After all, adults need a practical and chic way to store their lunch, too. It doesn't matter if you prefer to bring a sandwich, a hot lunch or even a few snacks to graze, there are lunch boxes out there for every eater. Some will keep your lunch cool even without an office fridge, and others will make your seemingly basic lunch salad a little more stylish.

What to Consider When Shopping for an Adult Lunch Box

When shopping for an adult lunch box, you'll want to consider your eating preferences. If you love salads then you'll want a box specifically designed for salads, or maybe a bento box is the best choice for you if you like a little bit of everything. Think about where your lunch will be stored: Does your office have a fridge? Will it sit at your desk? Will it be subject to a long commute? Does it need an ice pack? Also think about aesthetics and cost, too.
