I love OPI polishes, however they are a bit on the pricier side so I always wait until I see a good deal before I purchase.
I have many colours in my stash but my 2 latest purchases were Clean Slate and Rated Pea-G. They have such a great selection of shades it's hard to choose! I love how fast they dry and how long they last on my nails. You don't need a million layers like some other polishes and they have a beautiful glossy finish. Definitely keep an eye out for a sale!
OPI has some of the best nail polishes ive ever used they have such an amazing range of colours! I love to paint my nails and always find i always end up using the OPI nail polishes, they apply super smooth and you only need two coats, If i want the polish to last longer than a week I find adding the clear coat on top makes a big difference, this is also such a good option if your wanted to have nice nails and not pay so much getting them done at a salon and if your like me chips them the day they get them done :)
