Review on 🍺 Smuggle Ounce Collapsible Flasks True: Compact and Discreet Beverage Carriers by Joel Young

A tight seal when the security ring is removed from the underside of the cover. Slim design, looks beautiful. The carabiner is a little wobbly, but that's okay. The only thing that confuses me is that they don't seem to hold six ounces. I tested it by pouring the 50ml shooters into a bag, it didn't even fit a full two. 100 ml is only 3.38 oz and doesn't hold the whole volume. With two packs it will be around 6 ounces but from my test you are seeing a 3 ounce capacity more than 6 ounces. Still a good buy and very discreet, just plan on 3 ounces per pack instead of 6.
