Should I say that the case/packaging for the chain is in the cadboard box without the chain

^ This.

Upon opening the case/packaging, the chain was missing. Can the chain be viewed externally without opening the case?

I think you may be misinterpreting what I am saying. For example, if you were to order Airpods there is usually Apple packaging that holds the Airpods within a carrdboard box/envelope. Using this example, would I say that the Airpods were missing from the Apple packaging within the box/envelope, or that there was no Apple packaging entirely and what arrived was simply just an empty box/envelope? (This is just an example in terms of packaging, I understand that Airpods are too heavy to EB)
