If you don't already know, you can get a free bottle of Nails Inc nail polish, worth £11 each, with the December issue of Glamour Magazine (the one with Charlotte Church on the cover) for £2!
There are 4 colours in total: Warwick Avenue (baby pink), Hampstead Heath (dark red), Savile Row (deep plum) and Jermyn Street (taupe).
I got them all except from Jermyn Street.
All pictures were taken with 2 coats of each polish. They look slightly darker in real life than what they do in the pictures.
The formulation was great, I didn't have any problems, and the colours are opaque in 2 coats, apart from Warwick Avenue, there's still a slight visible nail line, it would maybe take 3 coats to become fully opaque.
This is a great bargain, you're paying £8 for 4 nail polishes that are worth £44 altogether.
Go out and grab these before they're all gone!
