Polish: L'Oréal Paris Pro Manicure

$5, drugstore.com

Tester wore during: Week of deadlines (lots of typing) and bathroom cleaning

Chip free days: 6 (without a topcoat)

Tester says: "The flat brush made it easy to avoid bubbles, which can lead to peeling. The color held on, and if I wore a topcoat, I'm sure it would last twice as long."

Why it lasts: Keratin, a protein found in fingernails, and plasticizers
