Question: Do these bottles say anything about being a "flask" or being used for holding liquid or beverages?  There's another product that does say that.
Document: No problems using these! Don't let anyone read the bottles too closely though because all of the fine print is funny but obvious that this is an alcohol flask and not actual sunscreen.
These flasks are awesome! Took them to Stagecoach and it was nice being able to bring two different types of alcohol in. Some people did say something about chugging from a sunscreen bottle, but these are a great idea for a flask
I bought four of these for me and my friends going to a music festival and you will get in with this, unless you have a pro at the gate. I am only giving four stars because it does say it is fake on the back, but nobody is going to read that. Also one of them started to leak but I suspect it was due to foul play and not the product design.
I bought this for spring break at Miami Beach because the local police were harassing people about having bottles of alcohol on the beach. The flask are easy to fill, they come with a funnel, but the funnel takes forever to fill the flask with. I just went ahead and filled the flask directly from the bottle, the opening is pretty wide so I barely spilled. Once they were both filled, I placed them in my cooler with ice and they cooled up nicely.
Brought to Coachella and people at our camp were asking why we were pouring liquor into sunscreen bottles. These are very convincing. We went through security with these several times and only lost one. One security guard made one of us open every container in the bag including the flask. The appearance of the the flask had nothing to do with it. Just bad luck.Having two different tubes is nice to identify things. We put dark liquor (fireball) in the dark tube and vodka in the light one.
I recently used theses at an outdoor music festival and they worked 100% of the time. Security never looked twice.The bottle does have silly statements on it that identify it as a flask but Who would exam someone's sunscreen bottle? The answer is no one. We actually found it easier to forgo the funnel that was included and to just use a steady had to pour directly into the bottle.After bring the flask in we would buy an overpriced soda/ lemonade/ etc and make a nice strong beverage.
These are awesome, most used at the beach. Good amount of alcohol stored in each. Very happy!
We used these to take some drinks onto a cruise ship and hand no issues. We were able to get off and on the ship with no delays.
Awesome product...they are monsters!
Great product and great service. Thanks!
Answer: They do say it in the fine print on the back but it's just filler wording to make it look like a real sunscreen bottle. Like it says if a security guard is taking the time to read this, you should run lol but it doesn't say flask on the front. They'd open the flask before reading the fine print
