Air • Jacob Bromwell®

IMPOSING, YET SLENDER

Minimalism is not about excess — it is about proportion, restraint, and the confidence to create the world’s thinnest solid copper flask without compromising material integrity.

Air embodies that discipline in its ultra-thin silhouette, delivering unmistakable copper craftsmanship in a form that slips effortlessly into a pocket yet feels grounded and deliberate in the hand. Its sleek lines and balanced geometry create a profile that feels architectural rather than ornamental — deliberate rather than decorative. Crafted from 22-gauge solid copper and refined through our ultra-reflective SuperPolish™ process, Air carries the same material integrity as our most substantial models. Inside, it is lined with molten, lead-free tin using our proprietary lost method, ensuring purity and longevity. Designed for purists who value restraint, Air proves that refinement is not measured in size — but in execution. Air does not compete for attention. It commands it through proportion alone.

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.
