What is the most expensive cartoon you have ever bought?

Although I like watching cartoons, I don't buy many cartoons around me. I didn't have much money when I was at school. The most expensive thing I bought was a picture book of the ghost of Bo Ying, which was particularly good-looking, high-definition big picture, super gorgeous, one or two hundred yuan. At that time, I hadn't bought a weekly anime weekly, but it was only five yuan, which was very cheap.

But it was the most expensive one I bought at school, and then my friend went to the comic-con exhibition and bought me a box of keys to the twelve constellations.

This is the key on Lucy's devil's tail. Maybe three or four hundred. Although it is not very expensive, it is really the most expensive anime I have ever bought. It is packed in an iron box. Each string of keys is very realistic, probably made of copper, which is quite weighty. It looks very retro. I will wear it on a chain at home and hang it in my study. Every time I read it, I can think of some scenes in comics. I guess this is also the most expensive cartoon I have ever bought in my life, because there is no cartoon to attract me after that.
