I will recommend use box with bubble wrap for fragile stuffs. Carriers will throw around the package and your package can be hit or pressed under multiple packages. Hope this can help you.
You don't realize how many people shipping CDs never, ever, saw a video like this and then they wonder why you come back at them later and tell them your stuff arrived with broken cases. I'm one of those person that will GLADLY pay for more shipping if it means my sh_t is safe. I'm looking at YOU, Amazon.
