About Iron Flask

Meals away from home are a lot more fun with Iron Flask. We designed our food jars to keep up with active lifestyles—that means premium stainless steel, double-wall vacuum insulation, and quality that will last a lifetime. A vast array of colors make these thermos food jars as tasty on the outside as they are on the inside, and two size options help you pack the perfect amount of snack.

Stainless Steel Food Jars

Iron Flask food jars feature high-quality stainless steel that will outlast plastic containers 10 times over. This is top of the line, 18/8 food-grade stainless steel, so it cleans up easily and will never impart off flavors. A powder-coated finish gives these food containers a modern matte look and a damage-resistant exterior that never sweats.

Vacuum-Insulated Food Jars

Whether it’s cold tabouleh for you or hot mac n cheese for your kids, double-wall vacuum insulation keeps your home-cooked meal just the right temperature, all day long. With Iron Flask, all you taste is your food, at the temperature you want to eat it.

Food Jar Sizes

Iron Flask reusable food jars come in 13.5 oz and 16 oz sizes, so you can mix and match for snacks, soups, or anything else you want to nosh on. The hardest part will be choosing between colors. Good luck!
