I've just got this set from Buyapowa, it cost me less than a tenner including postage. All four colours are gorgeous, a big thumbs up to OPI for this set. With top coat they are super sparkly, my photos don't do them justice but take my word for it - gorgeous! My fave is Get Your Number, mainly because I love this colour and I think is the sparkliest of them all. To the pics.....
