If you need to drink in secret, this disguised flask is your hidden alcohol solution. While it is not a particularly portable problem-solver, the Emergency Handbook Hidden Flask from Perpetual Kid is effective at hiding booze in plain sight in a room. From the outside it looks like a boring instructional tome on handling medical emergencies, but the inside is partially hollowed out to form a secret compartment holding a hip flask.
The cleverly disguised hidden alcohol container is made out of stainless steel and holds 7 ounces. In addition to being able to sterilize a wound, its contents can be used in a different kind of crisis. It will come in especially handy when hiding a little something away from nosy coworkers.
