OPI Nail Envy - Original Formula #NTT80

Followed instructions and put it on 2x day for a week - didn't make any difference other than dry my nails out further and give them a yellow tinge

Love it , but got 2 of same not 2 different colors. Kept it I will use it.

Opi Nail Envy and Repair Mode work exceptionally well on weak, thin, peeling nails to strengthen and lengthen natural nails.

Thank you for a great customer service

I can’t speak on the effectiveness yet. I also purchased Nail Envy in Double Nude-y, which is so thick it’s veritably chunky. That one is garbage. This one has a lovely consistency and fingers crossed that it actually works.
