How to create the look
Step 1
Apply the dark base
Start with one even coat of deep berry or black to add depth beneath the magnetic shade.
Step 2
Add magnetic polish
Apply a generous but controlled coat of blackberry cat-eye polish.
Step 3
Hold the magnet still
Position the magnet in one direction near the nail until a clean light ribbon appears. If you need a fine tool, this nail art brush and dotting-tool set covers the small details.
Step 4
Set one nail at a time
Set or dry each nail before moving on so the line does not drift.
Step 5
Protect the effect
Finish with a thin glossy top coat, keeping the brush strokes light.
Keep it intentional

Help it last
- Work one nail at a time for a crisp magnetic line.
- Keep the magnet close without touching wet product.
- Seal the free edge with top coat.
Remove it gently
- Remove with the method appropriate for your polish or gel system.
- Avoid picking at lifted polish near the sidewalls.
- Wipe away dark pigment carefully as you remove it.

Questions people ask
Do I need a special magnet?
A nail-art magnet is the easiest way to position the shimmer precisely.
Why does my line look weak?
Try a darker base, a fresh magnetic coat, and hold the magnet still a little longer.
Can I do a diagonal cat-eye?
Yes. Angle the magnet and repeat that same angle on every nail.
Does cat-eye work on short nails?
Yes. A small centred shimmer line can make short nails look especially neat.
