It could have just been a single shrink wrap. That’s probably how they produce marketing models before reprogramming the production line.
I never saw one mock-up of any product container. There are different groups that need copies: the marketing team, the print ad photographers, the ad video camera team, the hand model team, the packaging team, the store merchandising team, etc.
They may have only sent him one but they made a bunch for internal review before doing so.
