Upgrade your liquor canister to a Stanley Skull Ink Flask ($25). Made from durable stainless steel, the Skull Ink features a non-slip, rugged matte black finish and a wide-mouth opening so you can easily chug your preferred poison, straight up and without interference. Better yet, its slim, compact size makes it easy to slip inside your back pocket, so you can slam one anywhere, anytime, even during mass, your nephew's Bar Mitzvah or your book club meeting.
