The words “luxury” and “flask” might not seem like they belong in the same sentence, but once you hold the Air Flask from Jacob Bromwell, no other description fits. Made from 22-gauge solid copper and finished with an ultra-reflective SuperPolish™ finish, this flask is a true heirloom. Slim and minimalist, each one is 100% handmade and features minor imperfections that add to its unique charm.
