Not sure what they mean about refurbished. Came in a beat-up thin case, like the one’s rental stores use even though it shows the original case in the listing. The disk was completely covered with finger prints, but only had minor scratches, no way it had been polished as most refurbished disks are. Since shipping was included it was cheaper than eBay and it seems to work so far (have played for a couple of hours on three occasions). No instruction manual either, but it is downloadable from Nintendo.
