If there's one thing spies hate, it's turning their heads slightly to one side to look at things. James Bond keeps his head straight forward to avoid looking shifty. That's why this plastic 1-1/4" x 1-1/4" Spy Eye Right Angle Viewer is so useful. You just hold it up to your eye and no one knows you're staring at them. Rotate it and you can look in any direction. It's like the NSA, but for your face!
