Be super secretive about your alcoholic habits with the Binocular Flask. Enjoy on the go drinking with this super conspicuous booze dispenser. Bouncers will be none the wiser if you decide to sport this to the bar -- they'll probably just think you're make some outrageous fashion statement about bird watching.
That's another place where it surely would come in handy -- bird watching can be a bit dull, however a drink or two could fix that. The Binocular Flask looks like a pair of regular black binoculars, but instead of improving your vision, the alcohol you store inside will probably have the opposite effect.
Just make sure not to pretend you're using them in front of a crowd, because being a creeper is probably worse than being an alcoholic.
