Astronaut Key Light (Blue). Brand new, unused. When you press the button on its belly, the face part lights up blue. The batteries are replaceable, so you can use it repeatedly. I haven't used it since I bought it, so the insulating sheet on the battery compartment is still in place. However, I bought it several years ago, so I'm not sure if the batteries still work. Please be aware of this. #Takumi Kitamura
