No, but if you have the facility to apply new shrink wrap so it looks factory sealed, Amazon aren’t going to x-ray it to check what’s inside.
Hm, that's an interesting fraud vector. Presumably it applies to pretty much any retailer though? And doesn't apply to items with tamper-proof factory seals that are hard to counterfeit.
You only have to counterfeit it to the standard of Amazon's returned-items check though, not to the OEM's standard.
