How do you remove stickers from CD cases?
You just soak the sticker, wait a few seconds, and start picking at the edge with your fingernail. If the sticker repels moisture, only the outer edges will be affected. Sometimes this is enough, and once you start peeling the edge, the rest comes off easily.
What is the paper inside a CD case called?

Traycard / Inlay Card – This is the paper part that is embedded in the back of the case under the disc that is not removable. It usually has the barcode and track listing on it, and also has the side spine text (artist name) that you see when cases are stacked. It is perforated left and right.
