How do you choose a quality jewel case?

To choose a good quality polystyrene jewel case, you'll want to look at the amount of plastic used in the case and the amount of virgin material that is used. Quality cases contain more virgin plastic than poor quality cases.

So, your first clue to jewel case quality will be the weight. Heavier equals higher quality.

Your second clue will be clarity. The more recycled plastic you add to a jewel case, the cloudier it becomes. Manufacturers often add color to the case to cover up the cloudiness.
