naturally long and strong
I use all the Nail Envy colors. Never in my life (50’s)have my nails been this long and naturally strong. I’ve been using nail envy for about 6months. It’s incredible, i actually have to cut them shorter. I am so impressed and happy. The tech at the nail salon told me to not comeback for gel because my nails were too thin. Now I’m saving my money and never going back. I LOVE NAIL ENVY!

Poor Quality from Good Brand
This is quite possibly the worst bottle of polish I've ever bought from the OPI brand. It leaves streaks and chips easily (within 24 hours). The instructions say to apply 2 coats the first day, then on days 2-7 apply an additional coat, but the first 2 coats are ugly (streaked) and start chipping within hours. I'd return it if I could, but it was final sale (at $15!!).

Not a good experience for me
I would not recommend this product if you have ridges in your fingernails. I have used it faithfully for over 2 weeks, and 5 of my nails have split up the ridges, and chunks of the edges of my nails have broken off. I had to clip and file my nails way down to keep them from catching on my clothing.

DO NOT BUY THIS PRODUCT!
I've been following the exact routine for a month now. No changes in my nails, way over priced, and coverage sucks even with the repeated coats needed as directed.
