My pokemon cards are in storage as I had to leave them behind when I moved. Some are in plasic sleeves in a binder, while others are kept in plastic sleeves in a box.

My anime figures are displayed, not stored. I collect them for my own viewing pleasure, and not to sit there as a collection to collect value.

My sonic comics are all kept in plastic sleeves with cardboard backing on my bookshelf for convenient access when I want to read them.
