The BarryM crackle nail polish is the best thing i ever bought! It works and drys within seconds and gives an amazing funky pattern to the nails. The white also goes with so many different colours giving you loads of different looks for your nails. You can get this nail polish pretty much any where for £3.99. Im thinking of maybe trying one of the magnetic polishes by BarryM so let me know if you've tried it!
