Prometheus Design Werx AG Food Jar

Thanks to the double-wall vacuum insulation, this jar is designed to maintain hot temperatures for several hours. While exact performance depends on the starting temperature of your food and how often you open the lid, it is built to keep a substantial meal warm from your morning commute through your lunch break.

Yes, 28 ounces is quite generous for a food jar. It is sized to hold a hearty portion of soup, stew, pasta, or chili, making it a solid choice for those who need a substantial lunch rather than just a snack.

No. The jar is constructed from high-quality 18/8 food-grade stainless steel, which is non-reactive and does not retain flavors or odors from previous meals. You can switch between different types of food without worrying about lingering tastes.

The graphic is laser-etched directly into the surface, meaning it is permanent and won't peel, crack, or fade like a printed decal or sticker. It is designed to withstand the wear and tear of daily use and rugged environments.

While the stainless steel construction is robust, we recommend hand washing the jar to preserve the integrity of the vacuum seal and the finish of the laser-etched graphic over the long term.
