May 7 2010 Black nail polish and hair metal bands go hand in hand, and here's a little something to just blow you away-hey. It's Poison Nail Polish ($5), which, ahem, looks strikingly like OPI's Black Onyx ($8.50). As the product description proclaims, "If you're a fan . . . you've got to have a bottle of this!" So if you're a Poison lover looking for nothing but a good time (and who isn't really?), this black lacquer is sure to add the perfect amount of edge as you rock out. As always, the more chips you can attain, the better.
