The most talked about has to be the FashionistA range backed by The Saturdays, each of whom has their own colour:
I have two of the shades, which are now on 3 for 2 in Superdrug; All Fired Up Red (Rochelle) and Purple Me Up (Mollie). The polishes are £6 each and the magnet is £3.
I love, love, love the effect that these polishes give! It almost gives a hologram type of effect when you move your nails in the light, they are definitely a great take on the nail art trend. They are also really easy to use! Just paint one coat of the polish on, leave to dry and paint on another coat. Whilst this coat is still wet, hover the magnet over the nail to get the effect. I found that it worked a lot better doing the second coat and magnet trick nail by nail. This was the end result:
All in all I really like this range and I am definitely going to be picking up the other three colours while they are still on 3 for 2.
