The set is available at Selfridges for £19 and includes polish and skulls to bling up your nails.
As I'm not that into polish £19 seemed a bit steep for me, so I decided to test out a polish I had spotted while browsing the Rimmel stand.
Let me introduce you to my cheaper alternative, Rimmel stay matte top coat. I applied one layer of Essie 'over the edge' let it dry and then applied the Rimmel top coat over it.
The results are very similar to that of the Nails Inc leather polish, but a lot cheaper. I'm looking forward to trying this out with some of my other polishes.
