Shape, smooth, buff, shine--this multi-tasking buffer from Deborah Lippmann lays the groundwork for nail care. Use the numbered sides of Smooth Operator as follows: 1. Gently shape nail tip. 2. Gently buff ridges on top of nail. 3. Smooth nail surface before applying base coat. 4. Buff to high-shine when you don't want to wear nail polish. Do not buff to high-shine if you intend to paint your nails.
