To execute this classic look:
- Apply one thin, even coat of black gel polish over your cured base coat. Cure for 60 seconds.
- Apply a generous coat of emerald green cat eye gel polish over the black layer. Do not cure yet.
- Hold the rectangular magnet wand diagonally about 2–3 millimeters away from the nail surface at a 45-degree angle. Hold still for 5–10 seconds as the green magnetic particles cluster into a sharp, luminous line across the center.
- Flash-cure immediately under your LED lamp for 10 seconds to freeze the particle line before it diffuses.
- Complete the entire hand, cure fully for 60 seconds, and seal with a high-gloss non-wipe top coat.
