Spy Bolt Hidden Storage Safe

Even in the darkest corners of your closet, someone’s bound to eventually stumble upon your secret stash of valuables or sensitive data. So try the Spy Bolt instead. These real machine bolts turned hollow feature an O-ring seal for waterproofing, reverse threading on the bolt head for added security, and boast a storage compartment of 2.8 or 4.4 cubic inches – big enough, on the larger of the two, to keep rolled up cash, micro SD cards, and 4ml storage vials from prying eyes. Bonus points if you actually find a piece of furniture or a fixture in which to screw it.
