Love the OPI shade range for their nail polishes! Opaque and pigmented in colouring, one coat for a soft flush of colour on the nails and two coats will really make the colour stand out and pop.
The applicator brush is a nice size so it's not to large or small for easy application on the nails. And more importantly the brush doesn't leave visible streak marks.
The formula is on the longer wearing side for a standard nail polish and also doesn't chip as easily which is great. Has a very wide range of colours to choose from and they do cute collections of new shades like their new Barbie collection!
Opi nail polishes are one of the best I've tried. I love them. Pigmented, non streaky and last longer without chipping compared to others. Such good quality and an amazing variety of colours.
