I had bought this nail polish because I wanted 1 that is healthier than the normal one. I had asked Sally what was so special and she said it was healthier, I also told her that I can never keep nail polish for 1 hour. Nail polish doesn't keep with me. Sally told me that she keeps it with her for a few days, despite the fact that she spends a lot of time in water, brushes and works in racks and unpacks boxes. I thought which one should I try and No regrets, this is the only nail polish that will keep with me for several days. And this color is really beautiful. I am quite satisfied with this one.
