Right Angle Viewer Spy and Study Optics
These are really cool! My dogs and children do not know how I know what they are doing! They think that I have eyes in back of my head. Kids -watch for your parents coming! What a great inexpensive spy tool. Look through the window of the 1-1/4 x 1-1/4 inches (3.2 cm x 3.2 cm) plastic Right Angle Viewer and rotate it to see in any direction.
