You can find many iPhone cases in the market in $5 or even the lower. Of course, that is not a huge money compared to the price of iPhone itself. Spend an extra $10 for case can mean nothing.
But this Swarovski case might make you think twice before you purchase it. It is not most expensive iPhone case, but price is not that reasonable as well. Its cost is $239. The whole case is covered by various shapes of shiny Swarovski crystals. The design is unique and classy. So, I think, $239 is a reasonable price for this case.
