Secret Flask Looks Like an Ice Pack. Great Hidden Flask for Coolers, Discreet Flask for Work, and Disguised Festival Flask. Also a Reusable Flask and Disposable Flask (2)

I thought the fact that it wasn't remotely frozen would make it obvious, but it worked like a charm. It didn't even seem suspicious when I used it to "water down" my lemonade. I also purchased the sunscreen flasks, which they were onto. I have two complaints. 1) I had to hand it over when I wound up in first aid for forgetting to supplement this with food. Also, I'm not sure how this differs from a standard chill pack which you can get for just a few bucks.

Awesome product for the individual fed up with overly expensive prices for alcohol at venues. Pack one of these in a lunch bag or cooler, enjoy beforehand, and spend less time/money on drinks. I used my Amazon points to get this but I'd definitely buy more in the future as gifts for friends and family. Even if you don't get to use it at the beach or camping, still a funny gift for someone who drinks. Only regret is that I didn't come up with this idea haha.

Only real issue I immediately see - alcohol doesn't freeze at the lower temp that water does, so you will have an air bubble in this flask due to the design.Will it raise any red flags? Eh. I guess not, if tossed in a cooler and the inspector just glances in and sees food/drinks and chill packs. I doubt most people will be doing close inspections.Will update after I try to sneak into a minor-league baseball game with these!

First wash & the stickers were already getting all screwed up. Cleaning these is going to be a huge pain in the a**. The two little cavities next to the opening keeps trapping water when I was trying to clean it. Makes me feel like it won’t even be worth it to use.

Looks great, works great! Took on vacation so we could take alcohol down to the pool with us in our cooler. Didn't want to take anything breakable and it does look like an ice pack. Held up at least the 2 weeks we were in HI! We took it with wherever we went; threw it into the soft cooler bag with lunch, to the beach and pool, and sightseeing. Put what was left into the fridge for the next day. Yes, you can see thru the sides even tho they are not clear. Didn't seem to be an issue but you need to know. CON: see the shape? It is impossible to get everything poured out as some ends up 'stuck' in the lower corners when you are trying to pour. Hence, 4 stars instead of 5. A long straw took care of that problem when we needed to clean it (which we did by hand, again it was tough to get the last of the water out) but all in all it's a solid product.

I went to the San Diego Jazz festival and topped off my secret flask with rum and placed it right in the ice chest. When security asked to look inside they were no questions asked. The flask sealed tight and did not leak even after it was left in the chest overnight with melted ice, the water from the ice did not get in.

It's cheap looking. The sticker fell off when I rinsed it to prep it to fill it. I wouldn't try to sneak this in anywhere. I immediately ret it.

Perfect for universal. Went through without any issues. Use clear stuff.
