So you paint the varnish on as normal (I left one coat un-magnetised then applied another), then straight away while its wet hold the magnet (in the lid) over the nail... and this is the finished result...
Pretty cool, I really love it and at £5.99 what a bargain! Only thing I would say is caution if your like me and your varnish normally chips before you open the front door in the morning, because of the art effect, every time it chips you have to completely remove the polish and start again. It does dry super fast which doesn't make it such a pain in the arse.
All of the colours in the range were beautiful jewel colours, perfect for autumn.
