This bright pink/borderline red jelly is brightened up with pink/purple shifting flakies and iridescent glitter. 3 coats . You will probably still VNL because of the jelly nature of this polish.
These polishes have been worn repeatedly and have not caused any visible staining. Each person is different and all pigments have the possibility of staining so your experience may not be the same. I always recommend 1-2 coats of good base coat and top coat.
