China Glaze Magnetix

China Glaze, which makes nail lacquers sold at salons and professional beauty supply stores nationwide, has announced the launch of its limited edition Magnetix nail lacquer collection. Infused with iron powders that move when exposed to a magnet, China Glaze Magnetix uses magnetic force to create three different designs — starburst, repeating arrows or diagonal lines.

Available at brazilian nails too :)

OBS: The manufacture claims that you can use it at home,yes you can after practising a lot.  It sounds easy to apply but actually requires a little bit of technical skills to apply it properly.
