For being Sweden H&Ms polishes are cheap. They costs 39 Swedish kronor compared to an OPI polish that costs 150 Swedish kronor (about 21 US dollars). And for those 39 kronor you get a pretty good polish.
I bought No Mambo jambo the other day, going through H&M quickly on my lunchbreak (you know, H&M once started their first store in the city I live in). I fell for the emerald green color, it was beautiful, even there being stressed and all.
And I am not disapointed after wearing it on my nails. It looks just as beautiful on the nail. My nails shine with this on.
The formula was quite good and I used three layers to get full opacity. But, as one of my lovely readers warned me, it did stain my nails when I took it off, although I used basecoat.
