The listing, CASIO POCKET VIEWER has ended.
This is a Casio PV-200A 2 MB Pocket Viewer. I won this here on Listia, and it came to me just as it leaves me. There is no charger, no stylus, no instruction sheet. As you can see in picture 1, it does work. You can probably go to Casio's website and get instructions for it, maybe a charger also.
