Berry M Instant Nail Effects Magnetic
The darker the color the better you are going to see your magnetically activated design. This formula uses a magnet to activate the design. It is on the lid, but instated of actually making contact with the polish all you need to do is "hover" the magnet over to create the effect. Use a good base coat, apply two coats and then activate. This formula dries fast and is easy to use. Dark silver will show a cool wavy pattern and looks modern and edgy. This line gives you the most variety when it comes to effects. Choose from wavy designs or structured line patterns.
