eBaay seller kefkasdomain has a ton of really rare stuff up for grabs in their store, kefka in Game Paradise. A large portion of it is overpriced in my opinion, but they are extremely rare promo items. There’s too much to post here, but I’ll showcase a few of my favorites. You should also know there was a five cent listing day recently. I have a feeling that has something to do with why these are up.
Tons of other stuff too. Definitely worth a look.
