Sir Jack's is one of the best purveyors of luxurious home goods and gentlemanly essentials, so it's pretty unsurprising that they make one hell of a flask.
Crafted in the United Kingdom using lead-free pewter, the design is based on a vintage piece used by the British military and features an easy-to-open, diamond-knurled screw cap that's attached via hinge so you can't lose it if you tried. The mirrored finish gives it an extra dose of cool and the included micro-polishing cloth and flask funnel are incredibly welcomed.
Best part? It's on sale. Dropping from $99 to $79 for a limited time, this is a seriously stylish steal that's meant to last forever and only get better with age.
