This is something cool just to check out in case you ever need to pass along some “top secret” documents or information! Now this wax-based form of authentication has made its way to USB Flash Drives thanks to the team over at TopSecret USB. The TopSecret is built to hold a wax seal that allows the device’s recipient to immediately know if the information they receive hasn’t been compromised. You get your choice of 2, 4, or 8 GB Flash Drives in a range of colors as well as your choice of wax seal in the form of a classic letter to secure your data. They are available now on TopSecret’s online store and arrives in its own unique box.
