What items should have the protection of the flight case?

We know that the advent of flight case is because its role is an indispensable part of the demand pursued by air transportation. It is precisely because of this demand that the flight case came out. 

The flightcase can protect many tools and make many tools reliably protected, no matter what object it is. Whether it's mid-range, high-end or what it looks like, these tools are OK.

In particular, we need to know which items are inseparable from the flight case. 

For example, some vocal music equipment, such as audio tools, is inseparable from the flightcase. Like many bands, they often have to be placed on the plane because they have to tour. These musical instruments especially need the protection of the flightcase. There can be no negligence. It can be said that as long as they are tools with special purposes, it is best to place them in the flightcase in order to ensure their safety. 

Especially in medical instruments and equipment, stage lighting equipment, photoelectric equipment, audio-visual system, multimedia and military transportation packaging, these are high-tech equipment, which are inseparable from flight case.
