843 is a dark hot pink cerise shimmer polish with purple, almost blue toned shimmer within. Since it's KIKO's round bottle, the brush is of the round flat type which I really like. The formula is fine but sheer. If you have nubs 2 coats would be enough. I have 4 coats on here in a try to hide the VNL, but the 3rd and 4th coat looked pretty much the same, the base color remained the same on the nail bed since the second coat. I'm not a pink lover but this is a color I like, however CG's 2012 neons are still better, because I can't get this one to cover. I discovered after removal that it had stained my nails pretty bad though, so I'm not really recommending this.
Bought in a KIKO store for 1 euro on sale.
