Picked these polishes up on a whim about a year ago. They were on sale and I had a coupon, making them practically free. I had never tried them previously so I thought it couldn't hurt to try them out. I immediately fell in love before the polish had even dried. The first thing I noticed was the size of the brush. It was really thick compared to other brushes I had seen before. This made the application process so much easier. The polish is already decently thick, combine that with a brush that is thick and it makes for an easy, smooth and quick application. I did not have to go over any of my nails more than once. The combo of the brush and polish create a nice thick even layer the fist time there is no need for multiple coats. Because the polish is thick enough of its own I felt there was no need for a top coat and I was right. The polish still lasted around 7 days without a top coat which is an incredibly long amount of time for no top coat! I haven't picked up any additional colors other than what you see, but that is because I am not a polish hoarder. I recommend these to everyone.
