I love the bottle color of Cynthia. Sadly though it does not stay that color. She dries much darker and actually looks black in most light. I had no issues with formula or application. 2 coats achieved full opacity. Base coat was China Glaze Strong Adhesion base and Top Coat was Barielle Manicure Extender. Because Cynthia is such a deep blue there is potential for staining with longer wear.
Cynthia has potential, but falls a little to far on the black side to me. I may play around with this one a little or maybe use as a layering base.
