Don't be fooled by this slick ninja! Looks can deceive! For one, it's actually a 4GB thumb drive completely encased in a removable water-resistant silicone jacket. Secondly, it also conceals secret magnets that let it climb right up (ferrous) walls! Be aware: this USB 2.0 drive can hold 4 gigabytes of songs, photos, videos, term papers and more. Ninja Black.
