One is several bargain picks in a Poundland haul recently was O.P.I shatter topcoat. You can look at paying around £12 for one of these at full price, so quite a saving.
I found I had to apply one really thick coat for a decent shatter effect, such as on the index finger. On the middle and little fingers I just applied it to thinly, but the effect was quite cool as well, almost like a frosting. I love pairing gold and silver with pretty much any colour, as they more or less act as a neutral.
Are you hot for pink? Do you love a beauty bargain? Do you like to experiment with new looks?
