The NES cartridges of yore measured around 4 inches by 5.5 inches. While that may have felt clunky to gamers, it's close to the perfect size for this Legend of Zelda flask, modeled after the iconic gold cartridge from 1987.
The plastic container is a faithful replica of the original game cartridge, right down to the label. It can fit up to 5 ounces of liquid and even comes with a funnel and straw. Whether you're sneaking this into a video game convention or just sipping on it while playing Breath of the Wild, the cleverly designed flask is perfect for all your Nintendo-loving needs. You can get your own on ThinkGeek for $20.
