The best beginner magnetic nail effects are simple, visible, and easy to repeat. Start with cat eye stripes, velvet shimmer, or a magnetic tip accent.
Cat eye stripe
This is the easiest effect to read because you can see the reflective line move as the magnet gets closer.
Velvet shimmer
Move the magnet around the nail edge for a softer all-over glow. It is forgiving and works well on practice tips.
