This is pretty far out. The Top Secret USB is a thumb drive that is made of porcelain and comes in 2GB, 4GB, or 8GB models. The casing includes a small indentation where, once sensitive documents have been loaded onto the USB, a tiny amount of molten wax is poured and imprinted with a rather intricate design from an included metal stamp. Once the wax cools off, there is no way to open the drive and access files without breaking the seal — this ensuring no one has accessed your files. Indeed, this is a technique used by the ancients, and now fit for modern times. It is available for $46 (2GB), $52 (4GB) and $59 (8GB), in different colors, at its official website. All pretty decent prices, if you really consider what you’re buying.
