Will you spend hundreds of bucks to buy a mobile phone and then spend 20,000 bucks to buy a mobile phone case? If I have a lot of money, I might do that. This $ 20,000 iPhone case can be said to be extremely luxurious. 42 diamonds of 3.5 carats are inlaid on 18K gold, paired with rare golden fiber leather, plus a plate of 18K gold badge. It's gorgeous, but the price is really high. Click here to purchase.
