A steel hip flask is a small, curved, and flat container made of stainless steel. It is designed to hold and transport a small amount of alcoholic beverage, usually around 6-10 ounces. The flask has a hinged or screw-top lid that allows for easy opening and closing, as well as a small opening for pouring or drinking the contents. The exterior of the flask is smooth. Hip flasks are often carried in a pocket or purse for discreet consumption of alcohol while on-the-go.
