I use Orly colours, however, since being on the nail varnish thread, it would seem that no one else does.
The colours are awesome and the bottle even better with it's gripper cap.
I also use Calgel nail colours, and it has to be said that they are the longest lasting polish in the history of everness, my mum did a trial run on it for me and she does alsorts of house work etc... with no gloves I may add, and her nails stayed beautiful with no chips or peels for over 3 weeks. We had to take it off because it had started to grow off. Must admit cant fault it. Shame that the company charge such horendus postage to Jersey though, I can't justify the 40 plus quid it costs on a large order.
Lastly I use Cele nail varnish and in my opinion this is the best for coverage and that wow factor. It is so shiny it looks wet, even three weeks on, on my toes!
So theres my tupence.
Happy polishing
