What they've done is take a 2012 Nexus S and crafted a custom body for it made with aircraft grade aluminium, sapphire Crystal back glass and used precious stones for the buttons. This unit is in "like new" condition with very minimal signs from storage but I would rate it as 9.5/10 condition. The battery holds a very good charge. Comes with all original packaging and unused accessories. The internal of the box is made of metal.
Feel free to contact them yourself for additional confirmation if you want to as they are still a working company. You can see the IMEI on the photos - I have nothing to hide.
