Blud-1

Hi everyone! I bought a magazine with this polybag a long time ago. I didn't unpack it when I saw the inscription limited edition for collection and future sale, today while unpacking after moving I found it and noticed that it was already assembled, I started probing it without opening it and found some spare cases in it. I asked the gpt chat what this means, he said it could be a factory defect and advised to post on the forum to ask people, what do you think and how much could it be worth?
