AN AMERICAN ICON
Before luxury was branded and before heirlooms were marketed, there was Model One.

Since 1819, it has remained the benchmark for copper flasks — built with the same materials, methods, and proportions that established Jacob Bromwell® as America’s first housewares company. Recently recognized as “the best heirloom-grade EDC flask” by HiConsumption and "the best copper flask" by Business Insider, Model One continues to define the category it created. Crafted from heavy 22-gauge solid copper and refined through our ultra-reflective SuperPolish™ process, it carries undeniable weight and presence. Inside, it is lined with molten, lead-free tin using our proprietary lost method — a discipline preserved for generations. It arrives with both a historically accurate wood stopper and a modern cork stopper, honoring the past while securing the present. Model One is not a reinterpretation. It is the reference point.


Imperfectly Perfect: Minor imperfections lend charm, depth, and individuality to each piece and are a natural part of the 100% handmade process. Embrace the imperfect. This is the Jacob Bromwell® way.
