Torch™ Flask is double-wall insulated to temperature protect your spirits, it's made of electropolished 18/8 kitchen grade stainless steel to protect your whiskey for months-on-end, and it includes a magnetically attached 3 fl. oz. “sipping shot glass” to replicate your bar-top drinking experience wherever you choose to take it. Lastly, it features a removable bottom cap spanning the entire width of the flask for easy filling and cleaning. Fun fact, the removable bottom also allows you to add ice cubes to your flask, along with a chilled cocktail, providing you with a “pock-tail” wherever you choose to go. The tumbler itself is also double-wall insulated, so the entire flask itself is also suitable for hot beverages.
