Flask

“If you intend to hike more than five Middenmiles, take a small flask of beer with you.”
—excerpt from the hill dwarven guidebook, No Day Without a Beer, 950 FB

These containers usually consist of hardened leather and hold only enough liquid to ease one’s thirst on the road. A plug made from cork (or sometimes beeswax) keeps the bulbous or tubular flask closed, letting the owner attach the flask to a belt, tuck it into a garment, or store it in a backpack without fear of spilling its contents. A flask lashed to a belt cannot fall off, even while running or riding. Flasks also can be dropped safely without breaking when one must quickly draw a weapon. Inn and tavern keepers are accustomed to adventurers’ requests to fill flasks before they set out on long journeys. Some adventurers forget that they can fill their flasks for free at the local well or fountain, but then again, such adventurers probably don’t like to drink water.

Unlike water skins, flasks do not expand, cannot be folded up, and hold a relatively small amount of liquid.
