First of all, the colors are amazing, so props to OPI for that.
Where this falls down is its staying power, it just doesn't last, about a day or two later and it's chipping already, I've tried using their long lasting top coat, nothing helps.
Using this on my toenails is fine, it doesn't chip there.
Some of the colors can be hit or miss too, some aren't as opaque as they look in the bottle and some aren't as sheer as you might want. Overall I don't think it's worth it.
One of my top nail varnish brands! OPI is long-lasting and comes in such a nice variety of colours! The bottle lasts ages and it's fast drying which is so handy when i'm in a rush to do my nails. Love this brand
Tips: Ensure you do 2 coats for long-lasting nails.
