Here's a great set of of drink flasks that a lot of you might think are cool! They are perfectly modeled after the classic Nintendo Entertainment System cartridge. They were created by Ink Whiskey, and each one has been given a fun label, including Metal Beer, Super Bar-Hop Bros., CastleVodka, and Drunk Hunt.
Ink Whiskey is raising funds for production of the flask over on Kickstarter. People who pledge at least $20(USD) will get you a cartridge flask. If you pledge $50 or more you will get a gold The Legend of Drink edition, reminiscent of the gold Zelda cartridge.
