"Stop carrying bulky metal flasks and cumbersome containers. Disposable Flasks are the most convenient and inexpensive way to transport your favorite spirit or other liquids. Our flasks fit comfortably in your pocket or jacket. The flask is durable, compact, collapsible and lightweight. It stands freely when filled, empties completely flat and freezes safely. Holds approx 7.5 fl. oz. or 5 shots." I received a sample during Mardi Gras and love the product. I didn't have to worry about losing my flask or carrying it around all day or night. They have been great for golfing and concerts. Check them out!
