First of all, the brush in this polish is amazing- it's enormous! Very wide and quite flat (a slightly larger version of the 17 Supreme Shine brushes) with a lovely rounded tip, it's actually almost the full width of my little fingernail. It makes application SO easy and quick, I love it! If I see any more shades of this brand in my local pound shop I'll definitely be picking them up.
I am very pleasantly surprised with the formula too, as I said yesterday in my haul post, the colour is quite similar to No 7 Betty Blues, which is the only No7 polish I dislike- the formula is just bad (thick, gloopy and the colour doesn't show on the nail at all) and I can happily report that this is a good alternative, it only takes one thickish coat to get this shade opaque and the colour is just as lovely on the nails as it is in the bottle (though I think a little of the shimmer is lost if you're not in bright light, it looks pretty black in lower light)
As usual, I took way too many pictures, and I think they're all pretty... so here's a small selection:
