Buy the June edition of InStyle magazine (£3.80 with Eva Green on the front) and you'll get a free Nail's Inc varnish!
The varnish is full size (10ml), and comes in pale pink, light purple and light blue. These colours are designed specifically for Instyle. Nails Inc varnishes usually retail at around £11.
It is available from Thursday 3 May, until stocks last. I love these sort of freebies!
