Which childhood toy do you still keep and why?

I’ve been still keeping a lot of toys since I was kindergarten. I have different kinds of legos I’ve built, some dinosaur figures and some transformer robots. The reason why I’m keeping Legos is I feel like Legos are so precious to me because they were made with my spirit that’s why I can never give away. Secondly, I’d loved especially dinosaurs when I was kindergarten so I have many kinds of figures of them. I also love them. Lastly I liked playing with robots which transform cars. My mom gave some for younger kids she knows but I still have something great. Sometimes I play with that toys on my own. I think of them as my treasures.
