OPI is the renowned nail polish brand, however it lives up to its name.
After buying OPI I'm not likely to ever buy a cheap or different branded nailpolish ever again. I know I can trust OPI's quality.
They have a massive range of colours, styles and the number one thing is that they stay on for much longer and chip less frequently/quickly.
I find that if I use a top clear coat ontop of my OPI it can stay for over a week without chips.
OPI is constantly bringing out new colours and brands and ranges. They are on the exspensive side but are 100% worth it, I normally wait for sales to buy mine.
I love how there's so many different colours. The bottle is a decent size and defiantly lasts longer than most brands.
