It's revolutionary. It's so easy to use. Nic's Sticks by OPI are the latest and greatest nail polish technology, and it's going to change your life. It's a simple shake & pump pen that's as basic as a paint pen. The little brush perfectly spreads across your nail bed distributing color evenly for the most inept "color between the lines" ladies (like myself). Try it. Trust. You'll love it, and save tons on nail care.
