10 Best Stainless Steel Lunchbox Containers 2025 in the United States

The LunchBots Medium Trio II is a well-designed stainless steel lunchbox container featuring three separate compartments, which is great for keeping different foods like protein, fruits, and snacks neatly separated without mixing flavors. Its size is compact (6" x 5" x 1.75") and holds about 1.3 pounds of food, making it suitable for medium-sized meals or snacks on the go. Made from high-quality 18/8 stainless steel, this lunchbox is very durable and built to last, resisting dents and wear even with regular use. It’s also BPA-free and dishwasher safe, so cleaning is easy and safe for everyday use.

However, the container is not leak-proof since the lids and dividers don’t seal tightly, so it’s best to pack dry foods rather than anything with sauce or liquid to avoid spills. There is no insulation, so it won’t keep hot foods warm or cold foods chilled for long periods. At just over 11 ounces, it’s lightweight enough to carry comfortably in a lunch bag.

This lunchbox is ideal for anyone wanting a sturdy, eco-friendly alternative to plastic containers for dry meals or snacks, especially those who appreciate having separate sections without extra containers to manage. If you need leak protection or temperature control, you might want to consider other options.
