I love having nice-looking nails, but my always-on-the-go life doesn't leave much time for manicures, much less lay-about nail-painting sessions at home. That's why I love nail buffing, and the OPI 1-2-3 Luster Buff Board is the best tool I've found yet. The soft, gentle surface is great for smoothing out ridges and giving your nails a healthy, glossy glow—like a clear coat, but more natural. It will make your nails look polished even if they're not. You can buy one here for $5.95.
