Japan Texture is the name of these cases that are sold by a Japanese cellphone company Softbank. These cases are hand crafted and are known to be pretty expensive.  Above are the 5 designs recently released and they go for $1000.  They will fit the iPhone 3Gs or 3G.

JAPAN TEXTURE  series consists of a total of five cases with different designs. Created under the supervision of a historian, SoftBank says each case is covered with special lacquer and gold dust. It takes three to four weeks to make one, which kind of explains the price.

The main idea of these cases is to show how Japanese warlords from the Sengoku period would probably use their iPhones if they lived today. Each case comes with a specially designed pouch, a booklet explaining the historical background of the design and a storage box.
