I found Psychic High School in the back of my drawer and tried to open it but couldn't. I tried prying it open with my fingernails but it was locked tight. I tried wedging it open with a kitchen knife, but I didn't want to break it so I stopped. Forcing it was probably the wrong way to go about it. All the sides were different colors, and I realized I could twist and rotate each face and rearrange the order of the colors on the side. For now that will do. But I wonder if there's anything inside?
