i am a huge fan of picture polish collaboration line, and karma was made with probably the most famous nail polish blogger, sveta sanders, back in 2015.
karma is described as "a dark purple holographic nail polish with holo flakes". it is a perfect eggplant-purple type of shade, vampy and moody. it dries smoothly, and the scattered holo effect gives it even more depth.
i used base (china glaze strong adhesion) + two layers of polish + top coat (essence better than gel nails top sealer fast dry)
