Essie is one of my favourite nail polish brands. The majority of colours are very pretty and feminine and they have a lot to choose from. I would prefer a slightly larger brush but that is a minimal annoyance.
I own a few metallic shades which are brilliant! Completely opaque in one coat, although I do two for staying power, and they are non-streaky. The pastel shades I have last a long time on my nails without chipping. They go on very sheer with the first coat but build up to opaque in 2 or 3 coats. They also dry reasonably quick which is good and leave a nice hard finish.
I purchase my Essie polishes on eBay as I find it cheaper even with paying for shipping and they have all the colour range.
The problem I have with most nail polishes is that it comes on either too thick or too thin. Essie nailpolishes are soo easy to use because the brush is so versatile and can be applied thick or thin. When i first put it on the brush covers most of the nail.
Tips: The only thing about this nail polish is that the coats come out quite thin. You need to put on around 3 coats for it to look good.
