Ghostbuster Ecto Ad GogglesThese Ecto Goggles would be something every self respecting Ghostbuster should have in their possession! Good for detecting paranormal activity (using your imagination)! Goggles have one eye that lights up with a shade of "slime green" in one lens, and gives a realistic movie look! On off switch allows you to turn on the light, which requires 2 AA batteries. (Not included). The elastic headband holds the goggles securely in place. Features: Official
