It is usually used for movies and games. Distinctive appearance:
Slightly round corners and an opaque, roughened surface.
As in real life, you only need one cover bitmap here, which is then inserted virtually into the case.
This case is available in 6 standard colors. Of course you can also assign your own color to the case.

Change the spine width to calculate the recommended pixel dimensions of the entire cover bitmap.
For your presentation, you can also just adjust the transparency and shine of a given case standard color.
