Ragproper Leather Glass Hip Flask Set for Men & Women – Durable Whiskey & Liquor Flasks, Single Shot 3.4oz (100ml) + Double Shot 8oz (240ml), Premium Genuine Leather Cover, Black

Expensive but great quality. Because these are glass you can leave your booze in there for a very long time. I leave mine in the caravan for when we go away and the taste is just like it has come from the original bottle. Cleaning is harder with the leather but just wrap some kitchen towel round it and when finished washing just wipe the leather.

It's sturdy and I like the fact, I can see how much left in it thorough the glass.

My flask cracked on the inside after 1 use and the seller has not responded to my message of a warranty. Too expensive not to have a warranty

This is as far away from those traditional metal flasks as a Mercedes E550 is from a Yugo. First order of business is the design - these are glass, and a really nice gauge glass as well. Yes, perhaps a bit heavier, however there's a reason I don't keep Bourbon in a metal container. Glass is neutral (it won't impart any odd flavors) and it won't rust. In terms of practicality, very happy that it also allows me to see about how much I have left in the flask so I can get a refill. This particular set has a "double shot" (240 ml) and a "single shot" (100 ml) which in real terms means both will hold about a half a typical 750 ml bottle. Gracefully. The flasks are leather-bound with something that, well, isn't quite Hermes but it is very appropriate to the genre here. Really, it's quite striking, what with the leather binding a glass flask. Certainly attention-getting. I appreciate the inclusion of certain accessories here, namely two funnels (yeah, it's a good thing), two extra caps (plastic, not metal), and two silicone seals (to replace the included cork seals in both sets of caps). Me, I stick with the cork because I'm a traditionalist, however the silicone seals do an excellent job of preventing leaks. Very important during use because.... I took these out to a family event, and if you knew my family you'd understand why flasks are generally necessary. Loaded up both with Wild Turkey Rare Breed, something you really do NOT want leaking out. And these flasks performed marvelously. Easy to hold thanks to the indent, and trust me I held these flasks a LOT, with the glass telling me when I was out of Bourbon and, thus, time to leave the event. These are fantastic. Clearly a lot of thought went into not just the flasks but the accessories to include, and the entire package just works. An excellent product.

These guys thought of EVERYTHING. Every single detail is perfect. You don't even have to choose between sizes! I tended bar for over thirteen years, so I’ve seen A LOT of bar and cocktail products in my day. Most flasks are designed for style, but made with materials that will degrade your sprit. The initial selling point for me was that they are made of glass, which is completely non-reactive. This feature could have made these quite fragile, but the glass is sturdy and also protected by leather, so I don't anticipate that being in an issue. The cap can't be glass though... these come with two options (metal and plastic, presumably for times when one needs to pass through a metal detector,) plus cork and silicone liners! These are the two best materials I could possibly think of to maintain the integrity of the contents. The high-quality materials and craftsmanship elevate these well above all other flasks I’ve seen. Yes, $120 is a high price point, but in this case you get what you pay for in a market completely dominated by crap. For anyone who truly cares about the integrity of their drink, this is the holy grail of flasks. These will actually get used, which in my case, makes them a superior value to everything else on the market. Highly recommended for anyone with an educated palette, but such remarkable details would likely be wasted on your average Joe.

This company sells the same flasks but not leather (rubber outside) for $50. This one (at time of review) is $120.... and I really don't think there is enough difference in the product to make it over 2x more. They are great looking and work great. Pour smooth and feel good in your hand. I just can't justify the price tag when even the same company sells very very similar ones for way cheaper.
