Have a look at their list of items on prohibited items and no-compensation list. In essence almost everything that you can think of is on this list which in essence means that if you have a reason to claim you will be refused compensation. Shocking that this practice is legal, all you can do is use some other shipper and read their list of items not covered should an issue arise(the small print that most of us don't look at as we assume it will be fair, we don't have the time, it will be things like batteries/dangerous substances/firearms ect.) THIS IS NOT THE CASE WITH THIS COMPANY!!!- USE THEM AT YOUR PEARL!!!.
