I have an original case and manual for the game Spin Pair for sale.
Make me an offer. I'm thinking like $5 or something.
As a bonus I will include the HuCard for free. As far as I can tell it doesn't work. It just stopped working one day. I have tried cleaning it with no luck. If you can get it to work, hey, you got a great deal on the game.
Ideally, this would be for someone who already has a working HuCard but no case or manual.
