    Jelly?

    I’m not sure if this is part of the jelly collection I think it must be because it does have that sheer jelly effect. Anyway I’ve been eyeing up this colour for awhile and only just got it and I love it really good coverage but still has that jelly effect

    Lots of fun

    Its very true to colour and loving the consistency.

    Its very easy to use for nail art but will need about 2 coats to get the depth of colour you see in the product photo.

    So pretty!

    This blue is such a pretty colour, it has more of a jelly opacity, and is easily buildable.
