It's relatively easy if you do it right.

1. Wait for the 1:1 dummy to be available on eBay or Aliexpress (ex. : https://www.ebay.com/itm/403457957822 )
   
2. Open the box, replace the real phone with the fake one
   
3. Laminate the box with a thermal laminator
   
4. Enjoy
   

works with absolutely all devices, also Macs, just requires the purchase of the laminator

Though a vastly superior method, Why would you need the thermal laminator?
Why wouldnt you just open the box, recognize its a fake, email the company about it with proof?

Thank you for your contribution.
