Cat eye nails get their moving band of light from fine magnetic particles pulled into a line before the gel is cured. Tilt your hand and the band travels — the same optical effect that gives cat's eye gemstones their name. In a salon it takes magnetic gel, a magnet worked nail by nail, and a lamp. Here the band is already placed, by hand, in our SoHo studio.
Eleven shades below, from deep ruby and chocolate brown to smoke grey, champagne gold and milky white. Every set is reusable, applies in about five minutes, and comes off in seconds. New to the finish? Here's how the magnetic shimmer actually works.
