Tried out these nail-stickers from essence called Studio Nails. Not that easy to get a smooth surface the first time you try it (maybe gonna pre-warm them with a hair-dryer the next time), but I just love the foil-like look. And at 2 Euro for 14 nails you dont have much to complain about. A bit like Minx on the cheap (Minx are starting at 30 Euro I think). Sweet.
