For any 13-28-year-old woman in your life.

In case you haven't heard, nail polish is big business this year. And women everywhere are painting it on, changing shades in a moment's notice. After all, it's one of the easiest accessories you can wear. This 18-piece mini nail colour set from Sephora by OPI ($62) contains an incredible selection, from deep mulled berries to sunny Californian orange.  And while they are mini versions of the 0.5 oz bottles (weighing in at 0.2 oz each), the value is pretty incredible, since the regular size will cost you $10 for just one shade. And really, how often have you drained one single bottle of nail polish? Just don't ask me that question. *cough* Chinchilly *cough*
