FLIRTY is ridiculously gorgeous! This polish is in a CLEAR BASE with a variety of 6 bright neon colors scattered throughout it! All the colors of a rainbow! This polish looks gorgeous over many colors! In our opinion, it looks incredible over White and Black base coats too! Just remember to shake your bottle upside down in-between every few nails and these glitters will disperse throughout the bottle and attach to our fantastic flat brush. After you put a base coat color on, you should apply 1 to 2 coats of this neon topper on top of your base color choice. Please apply a thick top coat to seal in the glitter and allow for a smooth finish!
