Fans of OPI's Katy Perry black shatter polish will be excited to hear that the brand is now releasing three new "shattered" shades. In addition to the black, white, red and silver colours currently available, OPI will add turquoise, primary blue and navy blue to the line-up later this year. (They'll hit the US in May time so we can expect it to be a little after that.) Pop's a huge fan of blue polish and OPI's shatter shades so we'll get her to report on the new shades as soon as we have them. We're interested to see how a bright, standout colour like turquoise will look with the finish. Do you like the shatter effect? Are you keen to give these new ones a go?
