It’s an NES cartridge, it’s a flask, IT’S BOTH!
Well, it’s a flask anyway.
An awesome concept by Ink Whiskey LLC that was Kickstarted. There must be plenty of retro gaming drunks because it gained almost twice it’s original Kickstarter goal.
The flasks pay tribute to classics with parody names such as Bar-Hop Bros., Legend of Drink, and my favorite, CastleVodka.
