Review on 🍾 BellFlask 15 oz Non-Metal Plastic Reusable Flask - Concealable Liquor Hydration for Travel, Vacation, Sports, Concerts, Events - Pack of 3 Flasks (Black) + Free Filling Funnel - Patented Design by Heather Davis

Not as reassuring as picking out a silver hip flask from fine worsted wool or a worn denim pocket. These vials have a papery rustle, not a faint one. When empty, however, they almost completely collapse in weight and volume. And you can see how much is in it! Excellent! Mine don't leak, are very comfortable and come with a funnel. The 3 packs I bought contain a full liter bottle of my favorite whiskey and as they are matte black (rather than metallic) they are quite discreet. Enjoy.
