This is QUQU from Love Labu. I opened it after purchasing and attached it to my bag a few times, so I've disposed of the box and such. There are no included cards, etc., just the plushie itself. In the third photo, there's a slight stain, though it's not very noticeable. The one I purchased is from the initial production run, so the specifications are slightly different from the newly produced and re-released ones. It is definitely an authentic product.
