I LOVE OPI....they are my number one brand. I've used the regular nail envy on my nails for over 20 years and I recommend it to EVERYONE. I bought the thin and peeling version for my 11 year old. She is just starting to take an interest in her nails and they are very thin, peeling and papery. I have every faith in OPI as a brand and I'm sure that proper use (I shall be monitoring it's use) will soon strengthen and improve them.
