To recreate this design you will need:
Black, white and gold polish of your choice
Small striping brush
Tape (if you want a neat mani)
And a steady hand.
Once that is dried add white tips to the black nails and a black tip to the white nail.
Then with a black/white striper, or striping brush dipped in black/white carefully paint 2 black/white stripes on the tip. Then once that is dried add a gold stripe and top coat. Easy!
