Rabbit Hip Flask (Stainless Steel) This stylish metal flask holds up to six ounces of whiskey, bourbon or other adult beverage. A soft, silicone band helps provide a secure grip and tethers the flask's cap to the vessel. Constructed of polished, stainless steel, the flask is easy to clean and resists rust and corrosion. Great for camping, fishing or other outdoor activities. This flask should be hand-washed only; wash with warm water and a mild detergent and then let dry.
