Here's a set of Jap-tastic iPhone cases that are so expensive they come with their own slip-cover case (for your case). These stunning works of fine art take designers four grueling weeks to complete using special paints, lacquer and gold dust.
The fantastical price of roughly $1,000 each is justified by the use of an overpaid historian, with each case design connecting to Japan's rich pageantry of the Sengoku period (1467 to 1615).
Looks nice but a bit of rip-off.
They look awesome, but I fail to see why anyone would want to buy a case that costs more than the actual phone. Plus it is covered in lacquer and gold dust, which would last about ten minutes in my pocket. The case I got from http://www.uxsight.com/category/86534/iphone-cases.html is only $7 and it works ok.
