As a chronic nail-nibbler, I find that a glossy coat of polish keeps my finger tips pure an unadulterated. The polish junkie in me went a little crazy over these guys. Their polish, though pricey, ($18 a bottle, which isn't exactly impulse-style) comes in amazing trendy colors and is free of toululene, formaldehyde, and DBP. I'm going through a weird-color phase, most recently grey and before that was minty green, before that was gold glitter, so I'm in love with half of their colors. Fun!
