I have found my new love. Orly nail varnishes. Best nail polish I have ever tried. Colours are deep, big range, dries quickly. Normally they would cost £7 to £12 per bottle, but you can sometimes find some good offers on Ebay or other websites.
This particular colour (see picture below) is called Orly – Moonlit Madness. I applied only one layer there and it’s already looking good. Looking forward to buying some more!
