If you're a size 8 or 9 in footwear, you can now purchase the world's most expensive flip-flops. Artist David Palmer teamed up with footwear brand Chipkos to give you these one-of-a-kind hand painted sandals. For each pair sold at $18, 000 dollars, 100,000 square feet of Costa Rican rainforest is saved. The deed also gives you a two-night stay at the luxurious and eco-friendly Montage Hotel in Beverly Hills and a chance to meet-and-greet Palmer. The purchase also comes with a hand-made 18 carat eco-friendly gold Chipkos emblem, reclaimed wood and glass display case and other goodies. [Chipkos]
