Mariah Carey debuted her first collaboration earlier this year with OPI, introducing a new type of polish called “Liquid Sand”, where the finish is gritty and textured like sand. The line was a complete hit, and it’s no wonder that OPI came back for Round 2. Now she’s releasing a holiday line with gorgeous glitters, reds, and metallics that are sure to be a hit for the holidays. Check out the full line in the gallery.
