Ok so I would rate the colour nail polishs 3/5 they are ok. Nothing fab and the wear isnt too crash hot - they tend to chip quickly and take ageeeeeeeessss to dry. BUT they are cheap and often on special at K-mart so you can have lots of fun colours.
However this review as titled is about their top coat. I use it on top of most of my already purchased many nail polishs and love it. It has breathed new life into my collection - because that amazing black I have just got matte. Awesome.
I recommend getting a matte top coat and trying it out for yourself I was really impressed.
As mentioned above I was less impressed with the colours.
It's a cheap nail polish so don't expect it to last a while or to keep it's shine. The colours are great with loads of choices to choose from. I like the brushes, it doesn't leave the stroke lines that a lot of brushes do. After a while the product gets really thick in the bottle. I would buy it for a night out or something if I found a colour I liked. Not too amazing.
