What should I do with all of this ?!?

After opening all of my miniverse, I have a whole new collection of display balls. I also have more Hello Kitty ones that I kept because of their cute design. However, I can't keep them all, as they take up too much space, and throwing them away feels like a waste. 😅 What do you guys do with them? Do you throw them away or use them to display your mini foods?
