Any suspicious eyes will quickly look over your fake shampoo bottles and allow you to bring your flasks on any cruise ship. We do not condone any illegal uses, but like you, we hate having to use up our spending money on overpriced drinks. Each flask holds a whopping 16.9 oz and can easily be filled with our included liquor spout and funnel. When traveling, the internal seals paired with the screw caps prevent any leaking of liquid or odors. Once you are ready to drink, simply unscrew the cap and mix with your favorite beverage. This pack includes 2 hidden flasks so you can carry 2 kinds of alcohol around. We also include 4 heat shrink wraps to make the containers look even more realistic. The flasks will pay for themselves after one use, so get yours today Please remember to always obey all local drinking laws.
