As you may have already guessed, buying a luxurious leather case for your luxury perfume is going to cost you. The fragrances come in two sizes, 100ml and 200ml, which will run you $240 and $350 respectively, and don't include the travel cases, which start at $400 and go up to $500. But we suppose when you've already spent that much money on a scent, you might as well protect it from a careless bellhop as best you can.
