Just purchased a transformers prime first Ed. Entertainment pack off of ebay

Hello. I purchased the transformers prime entertainment pack from a high rates seller in eBay. A couple of days later I was messages by another eBay user about the item and how it was packaged and if it smelled like smoke. He had purchased a masterpiece sound wave from him that was supposed to be misb never opened. He doubted that because of dust and some other things. It is getting me worried about the item he sold me and if it really was misb never open as his description states. Comparing it to other sellers items from the open window on the box I can see the ties are exactly the same as the ones that I purchased. Would ties holding the figures be a hard thing to duplicate? There is tape on the top edges but I see in other listings the same thing. Is there any other way to tell? And my other question is does anyone still have this sealed in box? Again I am a casual collector and I just don't want to be made a fool of. Thanks
