In Superdrug, they have 5 new Barry M shades (that I could see, I don't know if there's more, I can't see anything on Barry M's website). They were Black Multi Glitter, Denim, Teal, Copper and Silvery Lilac. I of course, couldn't resist this one:
This is a black polish with tiny flecks of holographic glitter. I haven't swatched it yet though so I don't know how good it looks on the nail.
Denim is a bluey-purple glittery one, Copper a goldy-brown shimmer, Silvery Lilac was slightly like the Barry M Silver Foil Nail Effects I think, but with a Purple tinge to it, and Teal was an aqua coloured duochrome.
Also, there were 2 Barry M magnetic polishes, a black one, and a deep red one. The names of these escape me, but I think by the look of them, each polish has a slightly different magnet to create different effects on the nail.
Hope this was somewhat informative/useful! :)
