“Well, it is useful,” agreed Voddick, “but is it that much more useful than just having a canteen?”
Gollaon flipped the flask around. “Maybe not, my friend, but you must admit that it is fun to have.”
“That may be so but I would rather spend my money on good drink rather than a contain for the drink.”
“Which is why I did not pay for this.”
“You didn’t . . .” began Voddick.
“No, I did not steal it. I am to show it off and hopefully drum up business for the maker. Now, let us go and find some good sack, ale and wine to fill it with.”
Four Cornered Flask
These square metal flasks have a cap at each corner, usually marked in some way such as different colored enamel or inset metal, and feel very solid and weighty when handled.
Each cap opens into a separate storage area, capable of holding up to 2L (3.5 pints) of liquid and maintaining it at a drinkable temperature (4.5-65̊ c/40-149̊ f) indefinitely. It also retards, but does not stop, spoilage. Liquids placed in the flask will remain fresh and usable two-three times longer than normal.
