What is the main use of a Ziegler case?

The main use of a Ziegler case is as a protective container for shipping. This type of case is designed specifically to withstand the rigors of transportation, ensuring that contents are shielded from impact, moisture, and other environmental factors that could cause damage during transit. Their robust design typically includes secure closures and sometimes additional cushioning to enhance safety.

While these cases could theoretically serve other purposes, such as cosmetic storage or being utilized in a medical context, those uses are secondary and not the primary design intention behind a Ziegler case. By focusing on the key characteristic of protection during shipping, it becomes clear why this option is recognized as the main purpose of a Ziegler case.
