We get a lot of cool products in the mailbox here at Fat Boy Heaven, but this is one of the coolest in a long time. Sure to illicit a sense of nostalgia in any old-school gamer geek is the Concealable Entertainment Flask from InkWhiskey.com, a Portland company with an interesting idea.

Made to look exactly like the cartridge from a Nintendo Entertainment System, the flask is filled and poured via a hole concealed by a plug where you would grip the cartridge with your fingers. It requires a small funnel to fill, but otherwise works well, and does a great job of making the flask look like a cartridge.

Available in a wide range of novelty labels lampooning classic NES games, the Concealable Entertainment Flask is the perfect drinking accessory for the gamer geek on your gift list. It can be found for $20.00 at Ink Whiskey's website.
