Review (3/5): Not worth it, get it from somewhere else. I'd go to a physical vendor/nail salon for this one.
The gel is not a true cream and takes several coats to be decently opaque.
The gel and the regular polish do not match, the polish is about two shades lighter. Not going to work if you'll be using them side by side, but not really noticeable if gel is on the fingers and polish is on the toes. Also both polish and gel discolor after about a week, mostly rub off from dark fabrics/ink.
This seller will not take returns! "Needs special shipping for chemicals" aka, regular box, regular shipping labels and wrapped in bubble wrap on the inside. - I'm not impressed
