There are a lot of things we don’t know about the Drinkman Hip Flask. We don’t know how many fluid ounces of the good stuff it’s going to hold. We don’t know how much it’s going to cost. We don’t know if the nozzle is going to be on the top or the side, or even if it will be available in yellow. But none of that makes us want this thing any less. Cassette tapes are pretty much antiques at this point in time, but outside of actually mixing a tape there’s no real nostalgia for the archaic technology. How do you recreate that sense of euphoria you got listening to tapes? Drinking, of course. The hip flask will probably hold about five ounces, be the same size as the Walkman collecting dust in the basement and cost less than the liquor you want to put in it.
