A Cat Eye in the new Prismatic collection.

Limitless Key knows exactly what background song to set for her MySpace page.

This two-tone cat eye formula shifts between a light purple and green shimmer depending on the light, the angle, and honestly, the mood. One coat for sheer dimension. Two coats for the kind of depth that makes people stop mid-sentence to ask about your nails. Use a magnet wand to create the viral moon beam nails. No extra tools. No secret technique. Just apply, cure, and let it vibe.
