I was introduced to this product through a third party site and from my first use I was hooked. Not only do they offer wonderful shades for all skin tones but their nail colors are virtually harmless and don't contain harmful ingredients that are not only dangerous to your nails but to the environment period. I've also noticed with their nail products my own natural nails have become stronger and they look better. The nail color goes on smooth and it lasts a very long time. I also like that most of their colors are fairly opaque and don't call for many coats. The only negative I have with this product is the brush could be bigger but that's about it.
