Question: how many ounces are they?
Document: I was able to retrieve the flask, wash it off, and enjoy the totally untainted vodka within; it had clearly been stepped on many times, as the cap was scuffed, but it didn't break or unscrew.
I haven't had a chance to use them yet... bought them for our upcoming cruise... i've watched many "youtube" videos on demonstrations & I think it's a great idea - great to put in your shoes in suitcases. Can't wait - thanks!
Had to ask for a refund. The cruise came and went and two separate orders of these did not show up (ever). In the end I was glad because there are many less expensive ways to get the job done. I ended up using a camelback that I already owned.
Too small! I bought some last year and I assumed they would be the same size. I can only use the biggest of these flasks, the other 2 hold too little to even bother with. My fault though, I should have paid attention to the ounces which were clearly noted on the order page.
works perfect! saves a person a ton of money. a bit on the small side but gets the job done. 5 Stars!
walked around the vegas strip with these and no leaks, kind of reminded my of adult capri sun drink bags minus the straw. Although when I whipped them out it looked like I was drinking from a piss bag as I was told. Hey saved money on booze so Im happy.
used these for 3 cruises now worked perfect..and They do not Leak....! i highly reccomend this im about to but more as gifts
thought these looked bigger in the picture but they are pretty small and I may have to order any size.
thought it would be a little bigger...but it worked and got through on Disney cruise--saved me about $150...will order again!
these are nothing more then a plastic bag with a nozzel. why bother throwing a plastic bag of rum in your suitcase? you can now purchase rum and vodka in plastic bottles. all sizes. unless you want to smuggle your booze? as the name would suggest. But then there is this dimond plastic wedge that secures the nozzel to the bag. This diamond wedge will not fit in any smuggling device, say a empty bottle of hand lotion, contact lens cleaner, liquid hair spray?
Answer: yes
