As a tiny one, my little sister was fascinated by the comic book doings of one Selina Kyle, better known as Catwoman. If she ever starts nibbling her nails again, I think I may direct her to this DC Comics Catwoman Short Claw ($150). It may technically be jewelry, but it's really more the fanciest feline fingertip replacement out there and deserves to be recognized as such. Just think, for a mere $1,500, you could be menacing everyone around you with 10 digits worth of these, and you'd never have to worry about how your polish looked again. On the other hand, I guess it might be really, really difficult to do boring, normal things like use your keys, open jars, etc. Who really cares, though? You'll be too busy burgling and wearing knee-high boots to even notice.
