If you want to do manicures and pedicures with cat eyes effect you need specific nail polishes and a magnetic stick. That's what includes this set semi-permanent 'cat eyes' effect and gel nails: six polishes of six different colors and a stik magnetizer (which is valid for these polishes and for others with these properties if you decide to buy more in the future). Remember that to apply these polishes you need a UV lamp (like the one in the semi-permanent manicure kit at the beginning). Otherwise you will find it impossible to fix them.
