I got this from New Look for around £2.50 as I wanted a bright colour for a night out I was having, there are also darker colours to pick from.
They have a wide range of colours available but I decided to get the bright pink and at a later time got a dark blue. If bought in New Look students can get a 10% discount on it!

Packaging

It comes in a circle clear glass bottle which I like as it is different from the usual nail polish bottles available.
You can see the colour you are buying, black lid and the brand name around it.
The brush is quite strong but flexible so its easy to apply and but it doesn't fall apart.
They are easy to open - as long as you clean around the top with nail polish remover to stop it sticking.

Product

It is a good consistency when applying so it goes on easily and evenly, I prefer to apply two coats but you can apply one coat and still looks good, they are nice and bright on and a little shiny but not too much.
You do need a base coat or at least clear nail polish applied before using this as I've found the blue one as its darker stains my nails which is not a good look!
You should only use three movements to apply it once down the middle of nail and once at the sides to make it go on evenly and then apply your second coat in the same way.
Within a day it starts two chip and after two days half of the polish is off your nail, so apply a top coat and it keeps it a bit stronger for longer, but will still chip quickly.

Overall

They are quite cheap and you get a wide range of colours available to pick from, applied easily and the colours are nice and bright on and look really nice, the only down side is how quickly and easily they chip around the edges and can take a while to take off.
Despite that I still think they are worth buying!
