    Love this colour

    Just a beginner but absolutely loved these colours. Will definitely look a lot better once my nails grow a bit longer! Nice and subtle shades.

    Fun

    I really love the colour change; I find myself looking at them all the time to see when they switch colours. Very cool

    Really cool

    Absolutely adore the colour change.

    The picture supplied I feel doesnt quite represent the actual product.

    The pink is quite sheer so if youre looking for a more solid look, do a white base under.

    Nevertheless still a really cool colour.
