The flask, by nature, is a clandestine item. It slips in and out of interior suit pockets on the sly and offers secretive nips.
Why not bring an added dose of covertness to the whole ordeal with this All Black ZYX Flask? The stainless steel flask sports a mysterious motif that’s only boasted by the alphabet being curiously printed in reverse on the front. Each all black ZYX Flask holds 6 ounces of the good stuff. If an MI6 agent were to take a swig on the job, we'd like to imagine this would be his flask of choice.
