Most keychains are just that – they hold a bunch of your keys together to make sure you don’t lose them, and that’s that. Some of them come with a mini torch light, but what you see here is much more fiery as this is not called the Hamburger Shaped Butane Lighter Keychain for nothing. It retails for $2.90 a pop, and I doubt that you will be able to refill it once the gas is gone. After all, at that price point, you might as well get a new one, right? Just hope you don’t accidentally set your pants on fire with this.
