I read the reviews that said it was all anime stuff, but I was curious if that was actually common with this and tried it myself. But the same thing happened to me. It was all just anime that I don't even watch, and some anime I don't even recognize. Out of all 10-11 items I only kept one. And out of all the items I was only familiar with the characters in one. The one I kept was some super cute bear in a dress little figure, and it sits on a little plate. No idea what series of characters this is from, but I instantly fell in love with it. The other was a Sumikko hair tie, this was the only character series I was actually familiar with. Though not sure if I will keep this one. While I do use hair ties, I don't really know how to use ones with stuff hanging on them like this has, and don't see myself ever using it for it's intended purpose. All the other items were things from animes, multiple things from the same 2-3 animes or so. A lot of Demon Slayer, a lot of Jujutsu. I've never watched either before, but the characters and logos are recognizable. Then things from another one or maybe two animes that I didn't recognize at all.
This mystery bag would be better suited to having "anime" in the title tbh...
