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!!).

Bubbles
I bought this product to strengthen my nails after Gel polish removal.
My nails were weak and dry.
It burned when I applied it and seemed smooth.
But as it dried it produced bubbles.
I am taking it off today and returning product.

Bad product
I’ve been trying this product for months and it does not work. When I remove it my nails look worse. Waste of money.
