Maybelline's Superstay 7 days is my new favourite! I found it to be extremely long lasting with only a few tiny chips at the tips of my nails on day 7. So impressive! The polish applies smoothly, dries fairly quickly and with two coats you will have beautifully even and shiny nail colour.
I'm hoping they release some new colours soon so I can build a little collection on these beauties!
Have you tried this range? Are there any other long lasting nail varnishes you can recommend?
