This is called 'ultraviolet' - a bit of a misnomer since it's not a violet at all but a really pretty periwinkle blue. If you are familiar with Essie Bikini So Teeny and Illamasqua Cameo, this shade fits about midway between the two.
I used two coats here, with SV as my topcoat. I found this polish reasonably easy to apply; there was a bit of streakiness like you might expect for a pale cream like this, but nothing that SV couldn't easily smooth out at the end.
Another great thing about this polish is the price - £3.50. The bottles are 8ml - smaller bottles don't bother me at all, I've been painting my nails for as long as I can remember and I don't think I've ever used up a whole bottle. I prefer variety!
