I'll start with the blue colour which is called Dungaree Denim (buy here) which is actually the one I tried out last and still have on now. The application is really easy with your traditional flat top brush and it also dries amazingly fast which I guess has something to do with the different ingredients to normal nail polish. I've managed to get away with one coat here. It hasn't got amazing staying power and started to chip after about 3 days but I didn't use a base or top coat which may have helped. I was worried it would make it shiny again? I love the colour against my pale skin and am impressed with how pigmented it is.
The second colour I got is called Brutal (buy here) It has the exact same bulk standard brush as Dungaree Denim and again was quite easy to apply. However this one definitely needs two coats and it wasn't very true to colour compared with the pictures from the Topshop website. It did dry really fast which is handy but again it didn't last that long. A main downside to these nail varnishes was that after the third or fourth day the matte effect seemed to have gone and they were shiny like a normal polish. The first time this happened I thought maybe it was imagination but it happened with both and I'm not too sure why.
Overall I probably wouldn't buy these again as they are quite expensive at £6 and even more for postage too as my local store doesn't stock makeup.
